Abstract: The adoption of switching electronic converters for Adjustable Speed Drives (ASDs) can lead to some critical issues during operation. The presence of semiconductor switches like IGBTs and MOSFETs in Pulse Width Modulated (PWM) drives has increased the occurrence of steep fronted voltage surges (
