Power Unit parts diagram: 1 input rectifier, 2 IGBT power module, 3 tank capacitor, 4 matching transformer, 5 gate driver board, 6 bare PCB, 7 SMD passive (R/C/L), 8 power MOSFET. 12 parts in 8 top-level items. — Power Unit parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	Part	Qty	What it does
1	Input Rectifier	1×	Mains AC to DC bus
2	IGBT Power Module	2×	Resonant inverter bridge
3	Tank Capacitor	1×	Resonant tank
4	Matching Transformer	1×	Ferrite transformer matching inverter impedance to the low-impedance coil.
5	Gate Driver Board	1×	Drives the IGBT bridge and tracks the tank resonant frequency.
6	Bare PCB	1×	Inverter control board
7	SMD Passive (R/C/L)	1×	Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board.
8	Power MOSFET	4×	Auxiliary switching
