In this paper, we present and demonstrate a rotational energy harvester with a component-optimised maximum power point tracking (MPPT) circuit for adaptive power conversion. An AM-transmitter and receiver was used to instrument the harvester during operation. Experimental results on the effects of current limiting the harvester and the end-to-end efficiency of the MPPT circuit are shown. Finall...

Variable characteristics of turbine for different wind speeds have different operating point. Maximum power thus can’t be assured at all points of operation. But MPPT algorithm pushes the electronic dc-dc convertor to provide higher power output by adjusting duty cycle of buck/boost convertor connected before load. MATLAB simulations have been investigated and results show a higher power output...

This paper deals with the design and analysis of standalone solar PV based boost converter with P& O (Perturb and Observe) MPPT (Maximum Power Point Tracking) Techniques. An intermediate converter can therefore increase efficiency by matching the PV system to the load and by operating the solar cell arrays at their maximum power point. MPPT (Maximum Power Point Tracking) controller is used for ...
