BG2B

– Universal Gate Drive Prototype Board

Description: The BG2B is a two channel gate drive circuit for high power IGBT modules. The BG2B utilizes

Powerex hybrid gate drivers and DC-to-DC converters to provide efficient switching of modules rated up to 400A. The

hybrid gate drivers include high speed opto-couplers for control signal isolation and desaturation detection to protect

the IGBT from short circuit conditions. The hybrid DC-to-DC converters provide fully isolated control power for each

driving channel. The BG2B also provides an isolated fault feedback signal.

Features:

Applications:

BG2B is designed for use with Powerex NF- and

A- series IGBT modules.

 Use VLA106-15242 DC-to-DC converter for

operation with 15 VDC control power



Wide output voltage swing +15V/-8V

 Use VLA106-24242 DC-to-DC converter for

operation with 24 VDC control power
