Abstract

For the DC–AC input-parallel-output-parallel (IPOP) systems, the output current sharing control strategy is popular and effective to achieve output current sharing (OCS) among the constituent modules, and the average current control is usually adopted. The load current feed-forward scheme is incorporated into the average current control and the load current feed-forward node is located before the current-limiting unit, for not only improving the DC–AC IPOP system output voltage characteristics but also limiting the load current. The prototype of two-module DC–AC IPOP systems is built in the lab, and the steady-state and dynamic experiments are provided to verify the superiority of the proposed improved strategy.
