摘　　要：本文在传统变频装置的基础之上,采用三相电压型PWM整流器代替原有的电力二极管不控整流,从根本上解决了变频器整流单元对电网的污染问题。实现了电能回馈电网,以实现理想的四象限变频传动。利用TI公司的TMS320LF2407ADSP设计了双侧PWM电压源变换器硬件实现原理图,并给出了系统的软件实现。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. It can provide constant dc bus voltage and get low harmonic distortion of input current. The problem of power pollution by the rectifier cell of Frequency Inverter is essentially resolved. It also has line power feedback capability. The hardware scheme of three-phase PWM voltage source rectifiers using TMS320LF2407A DSP and the software have been introcixed.
