Abstract

Although increasing the switching frequency of variable speed drives provides higher efficiency and smaller size, the rapid changes in the states of the switches generate a common-mode (CM) voltage at the output of the inverter. The changes in the CM voltage result in CM currents. These CM currents are the source for problems such as bearing current, shaft voltage, and radiation from long cables [1]. Moreover, CM currents may cause electromagnetic interference within the surrounding environment [2]. These problems highlight the need for a method that can predict the CM current in all its flow paths.
