Abstract
Many problems should be considered in design of high-voltage power converter, especially the current control at the AC main and the output voltage waveform. Traditional non-controlled rectifier is non-linear, which is not conducive to optimizing the design of high-vokage transformer. Traditional VSI with single-phase inverter structure is not conductive to the improvement of the power hierarchy. In addition, the problem of common-mode voltage suppression exists in the rectifier and inverter. To solve the above problems, the PWM rectifier with power factor close to 1 and cascade inverters is proposed. All control principles are tested by MATLAB/SIMULINK.关键词
