Universal High Power IGBT Module Gate Driver Boar
d
BG1A-F kit contents: M57160AL gate driver and VLA106-15242 DC/DC converter.
BG1A-KA kit contents: VLA504 gate driver and VLA106-15242 DC/DC converter.
*The VLA504 replaces the older M57962L gate driver and the VLA106-15242 replaces the M57145L-01
DC/DC converter.
VLA504 / M57160AL
BG1A is a fully isolated gate drive
circuit board designed for use
with high current single IGBT
modules. When the board is
populated, a VLA504 hybrid gate
driver supplies the gate drive with
complementary emitter follower
power booster to provide efficient
switching of modules rated up to
1200A. The hybrid gate drivers
also provide protection against
unexpected short circuit
conditions. Isolated control
power for the driver is supplied by
an onboard VLA106-15242
regulated DC/DC converter. The
fault feedback signal is also
optically isolated.
