摘　　要：本文采用TI公司的定点DSP-TMS320F240作为主控制器。对三相50Hz逆变电源采用了瞬时值反馈控制与重复控制相结合的控制方法,利用瞬时值反馈控制抑制基波扰动,提高系统的动态响应过程;利用重复控制抑制非线性负载下的电压波形畸变,提高了系统的静态性能,使逆变电源输出电压波形质量提高。The TMS320F240 DSP provided by Texas instruments is selected as central chip in this paper The inverter is based on repetitive control and instantaneous feedback control. Instantaneous feedback control is used to reduce fundamental component disturbance and to improve the dynamic response process of the system; Repetitive control is used to reduce voltage distortion under nonlinear loads and also to improve the static performance. In this way, the inverter has high quality output voltage.
