INTERLEAVED POWER CONVERTER, AND CONTROLLER FOR INTERLEAVED POWER CONVERTER

摘要

PROBLEM TO BE SOLVED: To provide an interleaved power converter for converting a DC voltage source into a DC voltage output.;SOLUTION: The interleaved power converter comprises: two or more sub-circuits connected in parallel; driving means for driving a switching device of each of the sub-circuits to repeatedly switch on at a time t1 and off at a time t2; current sensing means for repeatedly determining an input current value by sensing the input current of the converter at a sample point; and control means. The control means comprises: comparator means for comparing the input current value determined at each sample point with the input current value determined at the preceding sample point, to obtain a measure of current imbalance attributable to one or both of the sub-circuits associated with the compared input current values; and current balancing means to compensate for the current imbalance.;COPYRIGHT: (C)2013,JPO&INPIT
