is optimization of the switching characteristics. The
switching characteristics are especially important in motor
control applications in which PWM transistors are used in a
bridge configuration. In these applications, the gate drive
circuit components should be selected to optimize turn−on,
turn−off and off−state impedance. A single resistor may be
used to control both turn−on and turn−off as shown in
Figure 31. However, the resistor value selected must be a
compromise in turn−on abruptness and turn−off losses.
Using a single resistor is normally suitable only for very low
frequency PWM. An optimized gate drive output stage is
shown in Figure 32. This circuit allows turn−on and turn−off
to be optimized separately. The turn−on resistor, R
provides control over the IGBT turn−on speed. In motor
control circuits, the resistor sets the turn−on di/dt that
controls how fast the free−wheel diode is cleared. The
interaction of the IGBT and free−wheeling diode determines

the turn−on dv/dt. Excessive turn−on dv/dt is a common
problem in half−bridge circuits. The turn−off resistor, R
controls the turn−off speed and ensures that the IGBT
remains off under commutation stresses. Turn−off is critical
to obtain low switching losses. While IGBTs exhibit a fixed
minimum loss due to minority carrier recombination, a slow
gate drive will dominate the turn−off losses. This is
particularly true for fast IGBTs. It is also possible to turn−off
an IGBT too fast. Excessive turn−off speed will result in
large overshoot voltages. Normally, the turn−off resistor is
a small fraction of the turn−on resistor.
