ABB 3BHB006338R0101 UNS0881A-P Gate Driver Board In-depth Analysis

Product Positioning and Core Functions

This module belongs to the UNS 0881A-P series gate driver board, which is designed for industrial power semiconductors (such as IGBT, SiC MOSFET). The core functions include:

Precise drive control: Generate high-speed pulse signals to drive power device switches, support ±15V/-5V typical drive voltage, drive current peak up to 8A, and adapt to 600V-1700V devices.

Electrical isolation and protection: The control side and the power side are electrically isolated through magnetic isolation technology (isolation voltage ≥3500V AC), and overcurrent, overvoltage, overtemperature protection and fault feedback functions are integrated.

Multi-channel collaborative drive: Usually 2-4 channels are independently driven (such as dual-channel IGBT bridge arm drive), and the delay deviation between channels is ≤30ns to ensure synchronous switching of multiple devices.
