Product Overview

The BD5935.48/61 3BHB017693R0001 is a dedicated IGCT gate drive board developed for ABB high-voltage variable frequency drives and power conversion systems. It delivers precise gate trigger pulses and real-time fault monitoring for integrated gate-commutated thyristors, controlling turn-on and forced commutation sequences. This unit provides galvanic separation between low-voltage control logic and the high-power power stage, while detecting device overcurrent, gate supply loss and abnormal switching events. It works as a core spare for medium-voltage drive stacks used in mining, steel, marine propulsion and large compressor applications, supporting reliable operation under heavy cyclic loads.
