Abstract
The scheme of single-phase PWM rectifier was presented on the basis of analyzing the principle of the single-phase PWM rectifier.Digital signal processor(DSP) TMS320F240 and 2SD315A were adopted in the scheme as the CPU and IGBT driver.The scheme can make full use of their advantages,simplify the design of the rectifier,and improve the performances.The experimental results verify that the designed rectifier can achieve the sine wave of AC current,realize the same phase between AC voltage and current,and stabilize the output DC voltage.
