DC-DC converter is widely used in power electronics. It is used in different kind ofdistributed energy sources such as solar cell, hybrid electric vehicle. For interfacingmicro-gird with main power grid DC-DC converters are widely used. The main task ofthe converter is to step-up or step-down the input voltage. Here a bidirectional DC-DCconverter is designed. For Smart grid technology, innovation in bidirectional DC-DCconverter is one of the most essential parts. The converter topology contains switched-inductor and switched-capacitor network, which gives the advantage of high voltageconversion ratio without using a transformer. The active switched network employs twoinductors/capacitors that charges in parallel during switch on period and discharged in series during switch off period. The topology is simulated in MATLAB/SIMULINKR2017a software. It is observed that the efficiency of the converter is 98% for boostand 97% for buck operation. The converter is controlled using PIC16F877a controller.Experimental results obtained from a 5W converter prototype confirm the theoreticalconsiderations and the simulation results.
