BG2A is a fully isolated two channel gate drive circuit designed for use with dual IGBT modules. The BG2A utilizes Powerex VLA500-01 or VLA502-01 hybrid gate drivers to provide efficient switching of modules rated up to 1400A. The hybrid gate drivers also provide protection against unexpected short circuit conditions using desaturation detection. The VLA500-01 and VLA502-01 hybrid gate drivers have an integrated DC to DC converter with 2500VRMS isolation to provide isolated gate drive power. Control signals are isolated using high speed opto couplers with 15KV/us common mode noise immunity. The BG2A provides an isolated fault feedback signal if a short circuit condition is detected.
