Improved Line Imbalance of Single-Switch Converter by Double - Switch Converter for Common-Mode Noise Reduction

Abstract

This paper aims to improve the system imbalance of the single - switch converters by employing the double -switch converter. The main objective is to analyze the cause of common mode noise generating in case of system imbalance and employing the double-switch converter for the common mode noise reduction. As the results, the ringing voltage and stress voltage of switching device are reduced. Finally, the experimental results in DC motor drive show the effectively improvement both time domain and frequency domain.
