Powerex Introduces New Universal Two-Channel Gate Drive Circuit

Powerex Inc. recently introduced the BG2C, a universal gate drive prototype board. Designed for use with high frequency optimized IGBT modules, the BG2C is a two-channel gate drive circuit.

The BG2C utilizes Powerex VLA507 and VLA514 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. BG2C is designed for use with Powerex NFH Series and CM***DUS-12F high frequency IGBT modules. It uses a VLA106-15242 DC to DC converter for operation with 15 VDC control power. It uses a VLA106-24242 DC to DC converter for operation with 24 VDC control power.

The devices are available from stock to 12 weeks from $83 ~ $108, depending on the rating.
