Introduction
To simplify the design of high power, high
performance applications, MICROSEMI
introduced a new advanced Dual IGBT
Driver.
Dedicated to drive high Power IGBT
modules (up to 300A, 1200V, 50 kHz) in
phase leg operation (as shown on Fig. 1),
this circuit provides multiple functions to
optimize IGBT performance.
This application note describes some
techniques to:
-Verify the driver capacity by the
total gate charge calculation.
-Optimize turn-on and turn-off
operation for switching losses
reduction by selecting the appropriate
gate resistances (R
G(on)
, R
G(off)
).
-Prevent cross conduction by the
input signal dead time calculation.
-Eliminate gate rigging in case of
paralleled IGBT modules operation.
-Understand the short circuit
protection operation including fault
output and reset in case of short
circuit detection.
-Explain mounting procedure.

Description:
Among other functions, this high speed
circuit integrates galvanic isolation of logic
level inputs signals, positive and negative
isolated auxiliary power supplies and short
circuit protection by V
CE(sat)
monitoring.
Due to the compact design, this circuit is
easy to mount on a PC board close to the
power module in order to minimize parasitic
elements.
Isolated screw-on spacers guarantee good
vibration withstand capability.
