摘    要:恒频恒压(CVCF)交流逆变电源一般用在比较特殊而重要的场合,其输出电压波形质量是衡量其性能的重要方面。该文分析了三相逆变电源输出电压波形控制基于旋转坐标系扰动内模原理方案的可行性,提出了旋转坐标系下基波扰动瞬时值控制内模与谐波扰动重复控制内模结合的方案。仿真和实验验证了该方案可以保证系统有较快的动态响应,稳压精度高,输出电压谐波畸变率小。

关 键 词:三相电压源型逆变电源  内模原理  波形控制  逆变器  反馈控制

Abstract:CVCF inverters are usually applied in critical situations, and the quality of output waveform of such inverters is one of the most important aspects for evaluation of its performance. In this paper a feasibility analysis of the control scheme of the three-phase inverters?output waveform is presented based on internal model theory in rotating frame. One scheme is present which is the combination of instantaneous feedback control internal model restraining fundamental component disturbance and repetitive control internal model restraining harmonic component disturbance. The simulation and experiment verify the scheme can work well. Fast response, highly accurate steady output and less distorted waveform is gained.
Keywords:Three-phase inverter  Internal model  Instanta-neous feedback control  Repetitive control  Harmonic distortion
