NOTES:
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.
Applications:
Features:
3A or 5A Peak Output Current
BG2C is designed for use with Powerex NFH
Series and CM***DUS-12F high frequency IGBT
modules.
2500VRMS isolation for control power and signals
