The scenario
Design of a full-bridge inverter for wireless power transfer, tuned for zero-voltage switching at 85 kHz using an H-bridge with series-resonant LC tank.
What is in this drawing
Read the decisions behind it.
01
Use four N-channel MOSFETs in an H-bridge configuration to generate the AC drive.
02
Include DC bus reservoir capacitor and independent gate drive supplies with gate resistors.
03
Add series resonant capacitor and transmit coil from the bridge output.
04
Place ZVS snubber capacitors across each MOSFET drain-source to support zero-voltage switching.
Reusable as a starting netlist for WPT transmitter power stages, induction heating, or resonant DC-AC inverters where ZVS operation is required.
