Summary:A new control scheme for current distribution in parallel connected DC/DC converters was presented in this paper, which combined the proportional integral sliding mode (SM) control with the Master-Slave current sharing technology to achieve both current sharing and a better robustness in a parallel dc-dc converter. And the stability condition of the closed-loop system was analyzed by using small signal method. A parallel buck converter experiment platform based on FPGA was constructed. And the experimental results of the given proposed method are compared with the traditional double closed loop PI control. Experimental results were presented, showing good dynamic performance of the proposed control scheme.
