BG2B-Universal Dual IGBT Module Gate Driver Board
Free Sample Board with purchase of Gate Driver and DC-DC Converter
Description
BG2B is a fully isolated gate drive
circuit board designed for use with
dual IGBT modules. When the
board is populated, gate drive is
supplied by M57159L, M57959L,
M57962L or M57160AL hybrid gate
drivers to provide efficient switching
of modules rated up to 400A. The
hybrid gate drivers also provide
protection against unexpected short
circuit conditions. Isolated control
power for the driver is supplied by a
pair of onboard M57145L-01
regulated DC/DC converters. The
fault feedback signals are also
optically isolated.
