N2 - This paper introduces a new topology for parallel balancing of serially connected batteries string. The main advantage of the balancing concept is that energy is transferred only when the cells are unbalanced. As a result, the power losses are significantly reduced since no current circulates through the system when balanced. This has been enabled by a modification of an isolated series-resonant converter operating in DCM and features zero current switching (ZCS). Another attractive feature is that one transformer for two cells is used, as opposed to conventional isolated topologies that require a transformer per cell. The realization is simple and requires simple current polarity detector. Experimental results have been obtained by a prototype of two series connected batteries, which demonstrates the balancing capabilities of the system.
