Design and Simulation of Voltage Booster Circuit Using Coupled Inductor

In this paper, a high voltage gain of DC-DC converter with design and simulation are proposed using coupledinductor. The proposed converter duty ratio is 0.65, so appropriate duty ratio is considering for this design of the converter. Due do more number of switches are considers for the converter circuit will make more switching power losses but in this converter using only two switches and have low voltage stress across power switches. The recycling processes are takes place in the coupled inductor, because of this energy stored in leakage inductor. The steady-state analyses and the operating principles with modes of operations of proposed converter are discussed properly in below detail. Finally the proposed converter design and simulation output are obtained in terms of output voltage is 271 voltages from the input of 24 voltage of the DC battery supply and output power of 407W and efficiency is 96.6% in designed and simulated using MATLAB/ SIMULINK.
