NOTES:

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:

1.5A, 3A or 5A Peak Output Current

2500VRMS isolation for control power and signals

Standard AMP MTA .100” input connector

Operates from a single 15 VDC or 24 VDC supply

Wide output voltage swing +15V/-8V

Compact Size 3 ” x 2.2 ” ( 76mm x 56mm)

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

? Use VLA106-24242 DC to DC converter for

operation with 24 VDC control power
