Abstract:In a two-stage single-phase inverter, the input current of the inverter contains a large amount of low-frequency ripple.In this paper, the energy flow, ripple power and the generation mechanism of the input ripple current in a two-stage single-phase inverter system are analyzed.Based on the small signal model of Boost circuit and the equivalent circuit model of ripple current, an input ripple current suppression method based on current double feedback channel is proposed.The control strategy is tested on an advanced digital control platform based on DSP, and the experimental results show the effectiveness and rationality of the control strategy.
