In this paper, a novel multi-input high gain (MIHG) DC-DC converter with PV and battery as inputs is proposed for minimization of commutation torque ripple in BLDC motor. The operation which is degrading the motor efficiency and overall performance mostly depends on speed and transient of line current in the commutation interval. For maintaining the outgoing and incoming phase currents, which are changing at the same rate during commutation phenomenon, a MIHG circuit topology and a dc link voltage management approach were used with brushless dc motor, which helps in mitigation of torque ripples while keeping speed constant. The dc link voltage control strategy is applied in the proposed (MIHG) converter for controlling voltage source inverter (VSI) input. The proposed topology is compared with boost and buck- boost which gives better torque ripple reduction during commutation and high voltage gain. Finally, simulation MATLAB/Simulink and experimental findings using dSpace 1104 microcontroller is used to obtained results, in comparison to buck, buck-boost dc-dc converter, the proposed method can obtain the output voltage=300V, which can drive the BLDC motor suitable for Erickshaw application.
