BG2C

– Universal Gate Drive Prototype Board

Description: The BG2C is a two channel gate drive circuit designed for use with high frequency optimized IGBT

modules. The BG2C utilizes Powerex VLA507 or VLA513 hybrid gate drivers and VLA106 series DC to DC

converters to provide efficient switching of modules rated up to 300A. The hybrid gate drivers include high speed

opto-couplers with typical propagation delay times as short as 200ns for control signal isolation. The hybrid DC

to DC converters provide fully isolated control power for each driving channel.

Features:

Ordering Information: BG2C-3015 is a kit with a bare BG2C board, two VLA507 and two VLA106-15242s
