Introduction In recent years,due to the rapid advances ofcomputer and communication,the power suppliesmust provide high current up to hundreds of am-peres and still have high efficiency and reliability.Under such requirements,multimodule- parallelingstructure is usually used and the load current isequally shared. The practical implementation ofthese distributed converters system is not alwaysstraightforward and various control problems arisebecause of undesirable interaction among subsys-t… 相似文献
