ABB GVC750BE101 (PN:3BHE009681R0101) is an IGCT gate drive unit for ABB medium voltage converters. It delivers high peak gate current and accurate turn-on/turn-off control for IGCT power semiconductor devices. It adopts fiber-optic command and feedback transmission to achieve complete galvanic isolation and strong EMC performance. This 750A-class gate driver board must work together with 5SHY3545L0009 IGCT module. Widely applied in medium voltage variable frequency drives, generator excitation systems, static frequency converters and STATCOM power quality compensation equipment.

ABB 5SHY3545L0009 (PN:3BHB013085R0009) is high-power 4500V press-pack asymmetric IGCT integrated gate commutated thyristor power module with integrated freewheeling diode. It features snubberless turn-off, low conduction loss and high switching reliability. It requires matching GVC750BE101 gate driver to realize high power conversion. Main applications include large medium voltage motor drives, gas turbine starting SFC, power grid reactive power compensation and industrial high-power rectifier and inverter systems.
