Abstract :
In order to construct a paralleled DC-to-DC power converter system with good performance of load current sharing and highly reliable configuration, a novel control scheme and three types of connection implementations of current balance controllers (CB controllers) are described. To perform the parallel operation of multiple different-capacity modules, the unification concept of CB controllers is presented. Finally, the prominent features of the load current sharing are confirmed experimentally for a three-parallel forward power converter system.<>
