Abstract: The ever increasing demand of miniaturization of DC-DC converters expects for the converters to be designed for higher frequency of operation with better efficiency. The recent developments in high frequency power switches and evolved technologies in magnetic design such as planar magnetics helps to achieve small size and cost effective DC-DC converters and their subsequent usage in space applications. In spacecraft level; the parameters like size, weight and cost of all the hardware plays a vital role. In such applications these low profile, high power density and efficient planar transformers in DC-DC converters realization will have a significant improvement in overall performance. This work deals with tuning free multiple tap planer transformers which enables us to have a broader range of output voltages for the designed configuration. It is highly reproducible with a better regulation, efficiency and less ripple content compared to the existing conventional transformer based DC-DC converters.
