MOSFET loss calculator
Estimate conduction, switching, gate-drive, output-capacitance, reverse-recovery, body-diode, and thermal losses.
Understand the loss modelEngineering tools
Power electronics calculators built for review, not guesswork.
Each tool opens the same validated calculation engine with a relevant starting configuration. Inputs stay in your browser, and the result can be traced through equations, substituted values, device losses, ripple, thermal estimates, and waveforms.
Switching loss calculator
Compare rise/fall-time, measured-energy, Qgd/gate-current, and manual switching-loss methods.
Choose a switching methodGate-drive calculator
Estimate driver power, transition time, peak current, dead time, and external gate resistance.
Review gate-drive equationsLLC converter calculator
Screen full-bridge LLC device loss, resonant behavior, current stress, ZVS conditions, and thermal margin.
Open the LLC guideCLLC converter calculator
Size a first-pass CLLC tank and review forward/reverse gain coverage, frequency range, circulating current, and ZVS.
