4 top-level parts · 185 parts in total · full bill of materials below

#	Part	Qty	What it does
1	IGBT Power Module	8×	Insulated-gate bipolar transistor module: a half-bridge or six-pack of power switches on one substrate that forms the switching stage of an inverter or drive.
2	Gate Driver Board 3 parts	2×	Circuit board carrying the gate driver ICs, isolation, and protection that switch the power modules of an inverter or servo drive.
3	Power Inductor	2×	Wound magnetic component that stores energy in switching converters, smoothing current and filtering ripple.
4	Microcontroller	1×	Single-chip microcontroller combining a processor core, flash memory, RAM, and peripherals such as timers, ADCs, and serial ports to run the device's control firmware.
