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:
 3A or 5A Peak Output Current
 2500VRMS isolation for control power and signals
 Standard AMP MTA .100” input/output connectors
 Operates from a single 15 VDC or 24 VDC supply
 Wide output voltage swing +15V/-8V
 Low parts count – Only 17 parts for two channels
 Compact Size 2.7” x 2.4” (69mm x 61mm)
Applications:
BG2C is designed for use with Powerex NFH
Series and CM***DUS-12F high frequency IGBT
modules.
 Use VLA106-15242 DC to DC converter for
operation with 15 VDC control power
 Use VLA106-24242 DC to DC converter for
operation with 24 VDC control power
