Variable-Frequency Drive parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat 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 IGBT Power Module 1× 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.
3 DC-Link Capacitor 2× Large film or electrolytic capacitor across the DC bus of an inverter or converter that smooths voltage ripple and supplies switching current.
4 Gate Driver Board 3 parts 1× Circuit board carrying the gate driver ICs, isolation, and protection that switch the power modules of an inverter or servo drive.
