Simulation of CPS-SPWM high-power inverter

Abstract

   Three-phase PWM voltage source rectifiers (VSR) are applicated to the Frequency inverter in place of conventional no-control rectifiers based on power diode in this thesis.The paper introduced fundamental principle of CPS-SPWM .expounded design of structure of double loop voltage type PWM rectifier system based on CPS-SPWM control. Thus understand that the CPS-SPWM technique can achieve SPWM technology of high power occasion, greatly improve the output waveform, reduce output harmonics, improve the equivalent switching frequency, optimize system performance. Simulink results show the system has good static performance and dynamic performance and CPS-SPWM is rationality.
