“…Relatively El Manaa Barhoumi demonstrated in [19], parallel combination of two boost converters is used to reduce voltage and current ripple under regulated load voltage. Researchers in [20][21][22][23][24] are using more than three switches which may lead to increased conduction losses, reduced voltage gain, creates manufacturing difficulty and increases the production cost which is not feasible. Hence, to improve standing gain and minimalize switching strain, novel topology proposed in this work uses Switched Capacitor (SC) magnetically CI technique and parallel grouping of Inductor-Diode (LD Technology) associated with the power switch.…”

This article showcases a new unique high gain step up DC/DC converter which is the future of interfacing to 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. The developed converter topology has reduced conduction losses, improved the conversion range, functionality with switched capacitor method with which reduced voltage stress during the switching period of the converter is achieved. Due to utilization of energy from leakage inductance of the new topology, mutually joined inductor will support to improve the efficiency and power concentration. Also, grouping of parallel inductor and diode L-D in series with the power switch helps in decreasing the switching stress current. When compared to existing converter topologies, the developed converter topology helps to produce output voltage of 505V for an input DC voltage of 30V, improved the voltage gain to 16.8 achieving the output power of 525W and efficiency to 97.74%. The voltage stress on the 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.
