GDBD 4410
Driver Unit for Converter-Brake-Inverter Modules
Preliminary data
Application and Features
The driver board constitutes a high performance interface
between drive controller and power section of a variable speed
AC drive, consisting of six plus one transistors for a three phase
inverter with constant voltage DC link and a brake chopper.
Pinout is especially matched to IXYS MUBW...7/8 or
corresponding industry standard IGBT modules.
The board provides:
? logic interface to the controller
- one control signal for each transistor
- feedback signal for fault condition
? magnetically isolated signal transmission from ground
referenced low side to high side potentials and vice versa with
high du/dt immunity
? one drive output to each transistor
- high current gate drive with negative off-voltage generated
on board
- U CEsat supervision for overcurrent protection
? protection schemes against
- overcurrent/short circuit
- cross conduction
- supply under- or overvoltage
? power supply inputs for
- either a single ground referenced supply voltage and bootstrap
circuits for the high side drivers
- or one single ground referenced and three single high side
supply voltages
It is intended for use as turn-key interface between controller and
power section.
The board uses IXYS proprietary driver IC chipset IXBD4410/
IXBD4411, where IXBD4410 is the low and IXBD4411 the high
side driver – see also the respective data sheet.
