【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.更多还原
