ABB 3BHL000385P0101 IGCT Power Module Unit

Module Feature

3BHL000385P0101 belongs to ABB HiPak IGCT series, serving as the core switching component of ACS6000 medium voltage variable frequency drives.

It adopts press-pack packaging, integrating IGCT chip, anti-parallel freewheeling diode and snubber matching structure. It features high blocking voltage, low on-state loss and high surge current tolerance. It must work with dedicated gate drive unit, widely used for medium voltage motor, compressor and pump speed regulation.

Working principle

The gate drive signal controls turn-on and forced commutation turn-off of the IGCT chip.

Together with rectifier and inverter circuit, it completes AC-DC-AC power conversion. The snubber circuit suppresses transient voltage spike during switching and protects the semiconductor chip from breakdown.

Onboard components

IGCT thyristor wafer, freewheeling diode, copper substrate, snubber assembly, high-current bus terminals, gate signal connector, insulated press-pack housing.

LED indicators

No built-in LED. Operating status and fault alarms are displayed on the drive control board and upper HMI system.

Hardware self‑diagnosis

Diagnostic functions are implemented by the matched drive control unit. It monitors overcurrent, overvoltage, overtemperature, gate drive fault and internal open/short circuit. Fault logs can be read via ABB DriveWindow commissioning software.

Programming software

ABB DriveWindow, used for converter status monitoring, fault history export and parameter maintenance.
