The Study on Suppression Common-mode Voltage Strategy Based on Predictive Control

Abstract

The traditional two-level pulse width modulation strategy will generate a higher common-mode voltage and cause common-mode interference to the inverter load-side equipment. This paper uses predictive control to implement current tracking control. The algorithm is simple to implement and can be adjusted by adjusting the value factor to suppress the common-mode voltage output of the inverter, and the simulation verifies the correctness of the algorithm, which has certain reference value for further research on the suppression of the common-mode voltage on the load side of the inverter.
