Abstract

Cell balancing is necessary for lithium-ion batteries and ultra-capacitors for high performance and reliability. A cell balancing technique implementing by bi-directional inverting zero-current switching switched-capacitor resonant converter is proposed in this paper. All transistors of the proposed circuit are switched under zero-current switching condition at any power level and voltage difference of the cells so that the EMI is low and the efficiency is high. There is no large magnetic device in the circuit. This technique can be applied on portable devices, industrial applications and electric vehicles. The operation principle of the proposed circuit is explained in the paper. The performance of the proposed cell balancing circuit has been verified.
