Abstract—This paper presents a reduction of ripple using π filter and c filter in bidirectional isolated dc-dc – dc converter. A typical application for this converter is battery charging for electrical vehicles, telecommunication and speed control of dc-motor. The advantages of the half bridge circuit with c filter are reduced ripple content present in the voltage and current waveforms, soft switching, low cost and high efficiency. The use of fuel cells is now envisaged to supply electrical energy in high power rail transportation application. The mat lab simulation results are compared with the experimental results.

Index Terms—Soft switching, micro controllers, bidirectional dc-dc converters, half bridge converters
