Abstract :
This paper reviews the instability problem and the analysis method for the paralleled DC/DC converters. Based on the review, a new stability analysis method for average and master-slave current sharing schemes is proposed. The proposed method is simple and allows straightforward design of a current-sharing loop compensator. The parallel of identical or non-identical modules can also be analyzed by the proposed method. Simulation results verify the theoretical analysis.
