Research on current-sharing control technique for paralleled converters

This paper first introduced the reasons of traditional paralleled converterpsilas not being current-sharing. The fuzzy logical control is applied to parallel converterpsilas current-sharing control technology by making an in-depth research and design on current-sharing looppsilas fuzzy logical controller. In order to reduce adjustable-range of current and make each modulepsilas current balance quickly, a middle current-programming automatic current-sharing technique is presented. Simulation results show that the proposed current-sharing control method can achieve better dynamic current-sharing and load-sharing characters, and can operate well within the large adjustable-load range.
