snubber circuits. Two such circuits, the RCD snubber circuit and the C snubber circuit, are
shown in Figure 1.31. This is becoming increasingly popular due to the circuit simplification
(FUJI 2004).
Note that the wiring inductance of snubber circuits is one of the main reasons for volt-
age spikes and, hence, the circuit should be built with the lowest possible inductance. The
detailed design of snubber circuits can be found in (FUJI 2004; POWEREX 2000). Here, the
design of the charge and discharge RCD snubber circuit, which is common in medium-power
