Inverter Stage parts diagram: 1 bare PCB, 2 power MOSFET, 3 gate driver IC, 4 power inductor, 5 DC-link capacitor. 17 parts in 5 top-level items. — Inverter Stage 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	Bare PCB	1×	Unpopulated printed circuit board: copper traces etched on an FR-4 glass-epoxy laminate that carry current between the components later soldered to it.
2	Power MOSFET	8×	Power MOSFET: a voltage-controlled semiconductor switch that turns high currents on and off at high speed in converters and motor drives.
3	Gate Driver IC	2×	Integrated circuit that turns a logic-level control signal into the fast, high-current gate pulses needed to switch a MOSFET or IGBT.
4	Power Inductor	2×	Wound magnetic component that stores energy in switching converters, smoothing current and filtering ripple.
5	DC-Link Capacitor	4×	Large film or electrolytic capacitor across the DC bus of an inverter or converter that smooths voltage ripple and supplies switching current.
