Abstract：In the two-stage single-phase renewable energy inverter system, the current drawn from renewable energy sources tends to be pulsated and contains harmful low frequency ripple components. This paper analyses the power flow in two stage single-phase power system and the mechanism of ripple power and ripple current in the input. Based on Boost DC-DC convertor small signal mode, the equivalent circuit model of ripple current is studied. A novel active input ripple current mitigating technique based on double channel current feedback is proposed by modifying the conventional voltage and current double-loop control method. Finally, a DSP-base experimental platform is built up with the proposed control strategy, and the results are provided to verify its effectiveness.
