Abstract :
The paper presents the implementation and experimental evaluation of a new current-sharing technique for paralleled power converters. This technique uses information naturally encoded in the switching ripple to achieve current sharing, and requires no inter-cell connections for communicating this information. Practical implementation of the approach is addressed, and an experimental evaluation of the approach based on a 3-cell prototype system is also presented. It is shown that accurate and stable load sharing is obtainable over a wide load range with this approach
