The purpose of the paper is to develop high accurate and unified maximum power point tracking technique that tracks the maximum power from both the photovoltaic (PV) array and wind energy conversion system, (an unified maximum power point tracking technique implemented for both wind and solar sources to track maximum power with higher accuracy).

In recent times, multi-input Direct Current- Direct Current (DC-DC) converter has attracted attentiveness, to conserve more energy and to achieve more efficiency. The kinetic energy of the vehicle is converted to electrical energy and further stored into the battery, during the regenerative braking (moreover, the battery gets charged during the regenerative braking process by converting the kinetic energy of the vehicle into electrical energy). During such a process, only the pulse width modulation schemes of the inverter are changed. To charge electric vehicles (EVs), two renewable resources as solar and wind are combined to produce electric power. Therefore, it was conveyed that the EV will be continuously getting power without interruption using various sources and regenerated power.

The performance and effectiveness of the proposed system are studied by extensive simulations and (are) validated using a prototype of the system. The results prove that the proposed system achieves an efficiency of 95.2%, which is higher than that of the multi-input DC-DC converters existing in the literature.

A novel multi-input DC-DC landsman converter for powering plug-in hybrid electric vehicles (HEVs) is proposed in the research. This method proposes a new cost effective and efficient technique for HEVs with brushless DC motors. Wind power, battery and PV panel are used as the input sources for the proposed converter.
