Product Overview

• Part Number: 3BHB003154R0101, compatible model GVC707AE01, paired power chip 5SHX2645L0004 IGCT
• Brand: ABB
• Applicable Equipment: ACS series medium voltage inverters, UNITROL generator excitation rectifier cabinets, high-power SVG reactive compensation equipment
• Type: IGCT integrated gate drive trigger board with absorption capacitor assembly

• FunctionThis board is the dedicated drive core matched with hockey-puck IGCT power devices. It receives optical fiber trigger signals from upper control boards, generates gate driving pulses to switch IGCT on/off accurately. It integrates RC snubber absorption circuit to absorb voltage spikes and restrain electromagnetic oscillation. Meanwhile, it collects device temperature, current operating status, feeds fault signals back to main controller, triggers overcurrent, overvoltage and overtemperature protection, guaranteeing stable rectification and inversion of high-power power loops.
