Traction Inverter (VVVF) parts and their functions
6 top-level parts · 19 parts in total · full bill of materials below
| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | IGBT Power Module | 6× | 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 | 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. |
| 3 | 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. |
| 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. |
| 5 | Gate Driver IC | 6× | Integrated circuit that turns a logic-level control signal into the fast, high-current gate pulses needed to switch a MOSFET or IGBT. |
| 6 | Inverter Cabinet | 1× |
