Abstract

In this paper a soft switching high gain dc-dc converter is analyzed and its closed loop control is done using voltage mode PI controller. The Converter will be having less input Current ripples due to its interleaved structure which is quite useful for renewable applications. Due to soft switching of the converter it will be having less losses and more efficiency. The converter uses coupled inductor which will have turns ratio less than unity for getting desired gain. By obtaining closed loop operation of the converter the efficiency of the converter is further improved and the optimal usage of the converter with variable source (renewable) and load conditions. The closed loop operation of the converter is simulated for 600w prototype using PSIM 9.0 and its waveforms are presented at different operating conditions.
