Abstract : This article develops a newly unique high gain step up DC / DC converter which is the future for interfacing to initiate rear bone of the fully green electric vehicle scheme. This technique optimally integrates four diodes, three capacitors and a modified coupled inductor connected to electric vehicle motor, which is three –phase Brushless DC motor. With this structure, reduced conduction losses, high conversion range and functionality with switched capacitor method and reduced voltage stress will occur during the switching period of the converter. Due to utilization of energy from leakage inductance, mutually joined inductor will support to kick efficiency and power concentration of the developed topology. Herein, the circuit configuration of DC/DC converter accommodating for electric green drive claims for even operation. A grouping of parallel inductor and diode L–D in series with the power switch is developed in this work. The converter suits extra beneficial conservative one by decreasing the switching stress current through the usage of new topology. The new topology results to increase the output voltage to 505V for an input DC voltage of 30V with voltage gain of 24.28, output power 525W achieving the efficiency of 97.74% by means of lossless power electronic semiconductor components. The stress voltage on switch, diode and capacitor is 170 V, which is 34 % of the converter output voltage. The designed converter is simulated using MATLAB/Simulink and the performance of the new topology is compared with different converter topologies.
