PWM inverter drive circuits using insulated gate bipolar transistors (IGBTs) have become the preferred standard for the variable speed control of induction motors because of their high reliability, good performance and relatively low cost. Despite the many benefits these drives offer, it is important to understand the consequences they can place on the motor insulation system. This is particularly important when considering the fast rise time of the inverter output voltage pulses when applied…
