Equations are screening models; validate final hardware with device curves, simulation, thermal analysis, double-pulse testing, and safe laboratory measurements.

1. How to use this guide

Start with the power stage

Choose the topology, enter its electrical targets, then use the preset only as a known starting point. Check current ripple and device stress before believing any loss number.

Use the best switching data available

Measured Eon/Eoff at comparable voltage, current, gate resistance, and temperature is preferable. Rise/fall-time estimates are useful when energy data is unavailable, but they are sensitive to parasitics and gate-drive conditions.

Close the thermal loop

RDS(on) rises with junction temperature, which raises conduction loss again. Iterate loss → temperature → resistance until the result settles.

Treat warnings as investigation points

A warning is not a component approval. Check absolute maximum ratings, repetitive transient capability, SOA, magnetics saturation, capacitor ripple rating, creepage, clearance, and protection response.

2. Parameter map

Datasheet conditions matter: a quoted 5 mΩ at 10 V gate drive and 25 °C is not automatically valid at 6 V gate drive and 125 °C. Use curves or a conservative measured value at the actual operating point.

3. Core electrical and loss models

Power and RMS current

POUT = VOUT · IOUT IRMS,ramp = √(IAVG² + ΔIpp² / 12)

RMS—not average current—sets resistive heating. The second expression is for a triangular ripple centered on the average.

Temperature-adjusted conduction

RDS(on)(TJ) ≈ RDS(on),25[1 + αR(TJ − 25)] Pcond = IFET,RMS² · RDS(on)(TJ)

The linear coefficient is a convenience. A normalized on-resistance curve from the selected device is better.

Switching overlap

Psw ≈ ½VDSID(tr + tf)fs Psw = (Eon + Eoff)fs

Use one method—not both for the same overlap energy. Energy curves or double-pulse measurements capture more real behavior than the linear overlap model.

Gate, output-capacitance, and recovery

Pgate = QgVdrivefs Poss ≈ ½CossVDS²fs Prr ≈ QrrVDSfs

Prefer Eoss/Qoss curves because Coss is nonlinear. Avoid counting the same energy twice if the switching-energy data already includes it.

Dead-time diode conduction

Pdead ≈ VFIcomm(2tdfs)

The factor of two assumes two dead-time intervals per complete switching period. Confirm the actual commutation sequence.

Thermal screening

TJ ≈ TA + PlossRθJA or TJ ≈ TC + PlossRθJC

Do not mix case-referenced and ambient-referenced paths. PCB copper, airflow, interface materials, and neighboring heat sources change the effective resistance.

Q1 · PWM
Load / power stage
Use this mode when the surrounding converter does not match a built-in topology and you already know the FET voltage, current, duty, and switching conditions.

Key computation

IFET,RMS = I · √D Pcond = I²D · RDS(on)

Worked example

Given
I = 10 A, D = 0.50, RDS(on) = 5 mΩ
Substitute
Pcond = (10 A)²(0.50)(0.005 Ω)
Answer
Pcond = 0.250 W

Important details and likely failure causes

  • Wrong current shape: the √D shortcut assumes constant current during on-time; use waveform RMS for triangular or resonant current.
  • Avalanche or excessive VDS: leakage inductance and layout can create turn-off overshoot.
  • Gate overstress or false turn-on: Miller current and source inductance change the real gate voltage.

Fully-on MOSFET

Static switchConduction dominated

Key computation

D = 1 IFET,RMS = I Pcond = I²RDS(on)

Worked example

Given
I = 10 A, RDS(on) = 5 mΩ
Substitute
Pcond = (10 A)²(0.005 Ω)
Answer
Pcond = 0.500 W
  • Insufficient gate voltage: the device can sit in its linear region and overheat.
  • Hot-plug SOA violation: charging a large capacitor can impose high VDS and ID together.
  • Thermal runaway: higher junction temperature raises RDS(on) and conduction loss.

5. Buck converter

Asynchronous or synchronous step-down

VOUT < VINCCM / DCMInductor output

Figure 3 · Buck power flow and labeled switches
VIN
QHS
main PWM
L + C
energy filter
Load
In a synchronous buck, QLS replaces the catch diode and conducts for approximately 1 − D, excluding dead time.

CCM equations

D ≈ VOUT / VIN ΔIL,pp = (VIN − VOUT)D / (Lfs) IL,RMS = √(IOUT² + ΔIL,pp²/12) IHS,RMS ≈ IL,RMS√D ILS,RMS ≈ IL,RMS√(1 − D)

Worked example: 48 V → 12 V

Given
VIN=48 V, VOUT=12 V, IOUT=10 A L=100 µH, fs=100 kHz
Duty
D = 12 / 48 = 0.25
Ripple
ΔIL,pp = (48−12)(0.25)/(100 µH·100 kHz)
Answer
D = 25.0% · ΔIL,pp = 0.900 A IL,RMS = 10.003 A

CCM/DCM boundary: the ideal triangular inductor current reaches zero when IOUT = ΔIL,pp/2. Below that load the converter enters DCM and the simple duty relationship changes.

Failure causes to investigate

  • Inductor saturation: Ipeak = IOUT + ΔI/2 can exceed the core’s temperature-dependent limit.
  • Shoot-through: QHS and QLS overlap because dead time is too short or Miller turn-on occurs.
  • Excess diode loss: dead time is too long, so the body diode carries load current unnecessarily.
  • Output ripple/heating: insufficient effective capacitance, high ESR, or capacitor ripple-current rating exceeded.

See TI’s synchronous-buck efficiency method, TI’s dead-time analysis, and IEEE analysis of common-source inductance and Kelvin source connection.

QMAIN pulls the switching node low during D. The diode or synchronous rectifier transfers inductor energy to the output during 1 − D.

CCM equations

D ≈ 1 − VIN/VOUT IIN ≈ POUT/(ηVIN) ΔIL,pp = VIND/(Lfs) IMAIN,RMS ≈ IL,RMS√D IRECT,RMS ≈ IL,RMS√(1−D)

Worked example: 24 V → 48 V

Given
VIN=24 V, VOUT=48 V, IOUT=5 A η=100% (ideal ripple example), L=100 µH, fs=100 kHz
Substitute
D=1−24/48=0.50 IIN=(48·5)/24=10 A ΔI=24·0.50/(100 µH·100 kHz)
Answer
D = 50.0% · IIN = 10.0 A · ΔIL,pp = 1.20 A
  • Excess switch voltage: QMAIN normally blocks about VOUT plus overshoot.
  • Inductor saturation: input current can be much larger than output current at high conversion ratio.
  • Output overshoot: load removal leaves stored inductor energy that must be controlled.
  • Diode recovery loss: reverse recovery can raise turn-on current and EMI.

Design and loss context: TI AN-1696 boost design example and IEEE datasheet-based MOSFET/diode half-bridge loss model.

Synchronous boost

QMAIN + QSRAutomatic complementary on-timeDead-time sensitive

Timing model

DMAIN ≈ 1 − VIN/VOUT DSR,ideal ≈ 1 − DMAIN DSR,on ≈ max[0, 1 − DMAIN − 2tdfs] Ddiode ≈ 2tdfs

Worked timing example

Given
DMAIN=0.50, fs=100 kHz, td=100 ns
Substitute
DSR,on=1−0.50−2(100 ns)(100 kHz)
Answer
DSR,on=0.480 · body-diode share=0.020
  • Reverse current: forcing QSR on in DCM can pull energy backward unless the controller detects zero current.
  • Shoot-through: complementary commands alone do not guarantee safe non-overlap at the MOSFET pins.
  • Body-diode heating: excess dead time or slow gate transitions increase diode conduction.
  • False turn-on: high dV/dt couples through Cgd; layout and sink impedance matter.

Dead-time and Miller-coupling guidance: TI, configurable dead time and dV/dt turn-on and Infineon, parasitic-induced false turn-on.

QHS and QLS must never be intentionally on at the same time. Current may commutate through either body diode during dead time.

Constant-current screening

IHS,RMS ≈ I√D ILS,RMS ≈ I√(1−D) VDS,rated > VBUS + Vovershoot

Worked example

Given
I=8 A, D=0.50
Substitute
IHS,RMS=ILS,RMS=8√0.50
Answer
IHS,RMS=ILS,RMS=5.657 A
  • Cross-conduction: propagation-delay mismatch, inadequate dead time, or dv/dt false turn-on.
  • Bootstrap undervoltage: high-side gate supply cannot refresh during long on-time.
  • VGS ringing: gate-loop and common-source inductance can exceed gate limits or retrigger the device.
  • Switch-node overshoot: power-loop inductance and abrupt current commutation create V = L·di/dt.

See TI’s detailed common-source-inductance loss analysis, Infineon’s VGS ringing/layout guidance, and the corresponding IEEE device-switching study.

One diagonal applies +VBUS; the other applies −VBUS. The control sequence must preserve volt-second balance and avoid same-leg overlap.

First-pass current sharing

IPRI,AVG-equivalent ≈ POUT/(ηVIN) IFET,RMS ≈ IPRI/√2 Pcond,total ≈ 4IFET,RMS²RDS(on)

For a real transformer current waveform, calculate RMS over each device’s actual conduction interval.

Worked example

Given
POUT=1 kW, VIN=400 V, η=95%
Substitute
IPRI≈1000/(0.95·400)=2.632 A IFET,RMS≈2.632/√2
Answer
IFET,RMS≈1.861 A per switch (simplified)
  • Flux walking: unequal positive and negative volt-seconds create transformer DC bias and saturation.
  • Wrong diagonal timing: logic or driver faults short the bus.
  • Leakage overshoot: transformer leakage and layout energy stress the FETs at turn-off.
  • Insulation breakdown: creepage, clearance, partial discharge, and transformer interwinding stress require a dedicated safety design.

For transformer loss and insulation context, see IEEE Transactions on Power Electronics: high-frequency transformer design with medium-voltage insulation.

Transformer
Lm, ratio n
Rectifier / SR

The tank’s impedance changes with switching frequency. Operation near series resonance often minimizes circulating current, while the required gain range determines operation above and below resonance.

Core normalized parameters

fr = 1/[2π√(LrCr)] Zr = √(Lr/Cr) Ln = Lm/Lr Qe = Zr/Re Mreq = nVOUT/VIN (calculator convention)

Definitions for Re, n, and gain depend on whether the primary is half bridge or full bridge and on the rectifier/load reflection convention. Keep one convention throughout the design.

Worked tank example

Given
Lr=40 µH, Cr=63.3 nF, Lm=200 µH
Substitute
fr=1/[2π√(40 µH·63.3 nF)] Ln=200/40
Answer
fr≈100.0 kHz · Ln=5.00

Design sequence

  1. Define minimum/maximum input voltage, output range, overload, hold-up, and regulation limits.
  2. Select transformer ratio so nominal operation stays near unity tank gain.
  3. Choose fr, Ln, and Qe; plot gain across input, load, and component tolerances.
  4. Check that the operating trajectory stays in the intended inductive/ZVS region.
  5. Calculate tank RMS/peak current, capacitor voltage, magnetizing current, core loss, winding loss, and rectifier/SR loss.
  6. Verify startup, short circuit, burst/light load, dead time, and control-frequency limits.
  • Loss of ZVS: insufficient magnetizing/tank current cannot discharge the bridge Coss during dead time.
  • Excess circulating current: poor Ln/Q selection or operating far from resonance raises copper and FET conduction loss.
  • Capacitive-region operation: can cause hard commutation and severe switching stress.
  • Transformer saturation: startup, asymmetrical drive, or excessive magnetizing current violates flux limits.
  • Resonant-capacitor overstress: high RMS current and tank voltage cause heating or dielectric failure.

With a symmetrical referred tank, forward and reverse operation can have similar resonant behavior. The physical secondary parameters must be referred consistently through n.

Prime marks denote quantities referred to the chosen side. Confirm how your turns ratio n is defined before applying n².

Worked resonance example

Given

Substitute
fr=1/[2π√(30 µH·84.4 nF)]
Answer
fr1≈f′r2≈100.0 kHz

ZVS energy screen:

½LcommIcomm² ≥ ½CeqVbridge²

This necessary-energy check does not prove ZVS; nonlinear Coss, dead time, magnetizing current, device capacitance, and the exact commutation path must be included.

Design sequence

  1. Specify both power directions, voltage ranges, power levels, and startup/precharge states.
  2. Select transformer ratio near the nominal DC conversion ratio.
  3. Choose a tank symmetry/reference convention and solve forward and reverse gain surfaces.
  4. Sweep L/C tolerance, magnetizing inductance, load, and dead time; identify ZVS boundaries.
  5. Check all four bridge legs, both resonant capacitors, transformer, and controller transition states.
  • Forward/reverse mismatch: referred tank values or controller limits satisfy only one power direction.
  • Light-load hard switching: commutation current is too small to move both bridge-node capacitances.
  • Tank tolerance split: L/C drift separates the intended resonances and increases current.
  • Mode-transition surge: direction reversal without coordinated phase/frequency/current control causes excessive tank energy.
  • Capacitor or transformer overheating: high circulating RMS current is missed when only output power is considered.

The slow leg changes with line polarity. The high-frequency leg shapes inductor current to follow the rectified line. Real implementations require line sensing, current control, protection, inrush limiting, and safe isolation.

First-pass equations

POUT=1 kW, VAC,rms=230 V, η=95%, PF=0.99
Substitute
Iline,rms=1000/(0.95·0.99·230)
Answer
VAC,pk=325.3 V · Iline,rms≈4.624 A

Mode selection: CCM has lower peak current but hard-switching/recovery challenges. Critical/boundary conduction turns on near zero inductor current but varies frequency. DCM has an interval of zero current and higher peaks. The controller, EMI filter, magnetics, sensing, and loss model must match the selected mode.

  • Zero-crossing distortion: polarity handoff, dead time, minimum on-time, and current-sense offsets distort line current.
  • Fast-leg shoot-through: timing or Miller turn-on directly shorts the HV bus.
  • Reverse-recovery stress: a silicon MOSFET body diode in hard CCM commutation may produce prohibitive current and loss.
  • Bus overvoltage: load removal or control-loop error overcharges the output capacitor.
  • Inductor saturation: low-line peak current, startup, or fault current exceeds the magnetic design.
  • Unsafe construction: mains circuits require fusing, inrush control, isolation strategy, spacing, enclosure, and applicable compliance review.

11. Input/output ripple and passive stress

Capacitor voltage ripple

vripple(t) = (1/C)∫iC(t)dt + iC(t)·ESR ΔV ≈ ΔQ/C + ΔI·ESR

The capacitive component follows charge balance; the ESR component changes immediately with capacitor current.

Capacitor heating

Pcap ≈ IC,RMS²·ESR(f,T)

Use the ripple-current spectrum and frequency/temperature-dependent impedance, not only a DC ESR number.

Inductor copper

PCu ≈ IL,RMS²·DCR(T) + PAC winding

Skin and proximity effects raise winding resistance at switching frequency and harmonics.

Core loss

Pcore = f(B, ΔB, waveform, material, volume, temperature)

Use manufacturer loss curves or a waveform-aware model for the actual core material. A single generic Steinmetz fit may be inaccurate for nonsinusoidal excitation.

Capacitor application caution: Murata’s polymer-capacitor design guidance. Magnetic modeling research: IEEE core-loss calculation method for DC/DC power converters.
