摘要：
For the problems of traditional LCL-type grid-connected inverters have resonance spikes and grid-connected inverters of split-capacitor single-loop control have low power factor. A novel dual-current loop control strategy is proposed in which the split-capacitor intermediate current is used as the inner loop and the grid-connected current is used as the outer loop. The simulation results of Matlab/Simulink are given. The simulation results show that the LCL type single-phase grid-connected inverter can achieve low-harmonic and high-power factor grid connection using this strategy, which verifies the feasibility of this control strategy.
