Abstract

This paper aims to obtain a hybrid algorithm to suppress the common mode voltage (CMV) while suppressing high frequency harmonics for the three-phase voltage source inverters (VSIs). The common mode interference noise caused by CMV and high frequency switching noise caused by PWM control switch on and off will cause electromagnetic interference (EMI) to the system and affect the electromagnetic compatibility of the system. The sources of CMV and high frequency switching noise of VSIs are studied in this paper. This paper proposes a hybrid algorithm which can suppress both CMV and high-frequency noise. The correctness and effectiveness of this method are confirmed by experimental results.
