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 Stack 1× Switching module that synthesizes variable motor frequency.
3 Power Supply 1× Unit that converts mains or battery input into the regulated DC voltages a machine's electronics and actuators need.
4 SMD Passive (R/C/L) 110× Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board.
