BG2A-NFH

BG2A-NFH is a universal gate drive prototype board. BG2A is a fully isolated two channel gate drive circuit designed for use with dual IGBT modules. The BG2A utilizes 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 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.

• Built in isolated DC to DC converter for gate drive
• Propagation delay time 0.4us (Typical)
• SIP outline allows more space on mounting area
• Variable fall time on short circuit protection
• Electrical isolation voltage between input and output(2500Vrms for 1min)
• CMOS, TTL compatible input
