In this paper, a DC-DC switched capacitor (SC) converter without using transformer is designed to achieve high voltage gain. Normally a transformer is used for AC-AC power conversion with step up or step down operation without changing the frequency. But it occupies more space due to its size and weight. Therefore, switched capacitor is used for achieving high voltage combine with converter, in order to avoid the transformer due to more expensive and losses. The traditional converter consists of more switches and stresses as well as losses with converter. In proposed converter, it uses fewer amounts of switches and gives high efficiency to increase the voltage gain. The current ripples are filtered that help to device life time and also reduce the electromagnetic interference. The designed converter is analyzed and the voltage is attained using MATLAB/Simulink.
