This paper presents technique for battery charger to achieve efficient performance in charging shaping,
minimum low switching losses and reduction in circuit volume .The operation of circuit charger is switched
with the technique of zero-current-switching, resonant components and append the topology of dc-dc buck.
The proposed novel dc-dc battery charger has advantages with the simplicity, low cost, high efficiency and
with the behaviour of easy control under the ZCS condition accordingly reducing the switching losses. The
detailed study of operating principle and design consideration is performed. A short survey of battery
charging system, capacity demand & its topologies is also presented. In order to compute LC resonant pair
values in conventional converter, the method of characteristic curve is used and electric function equations
are derived from the prototype configuration. The efficient performance of charging shaping is confirmed
through the practical examines and verification of the results is revealed by the MATLAB simulation. The
efficiency is ensured about 89% which is substantially considered being satisfactory performance as
achieved in this paper.
