Abstract :
A MPPT is required for effective operation and power extraction from a PV module. Amongst several existing well established MPPT algorithms, the open voltage (OV) based algorithm is chosen to design the proposed MPPT circuit developed in this paper. The designed circuit is simple and easy to implement yet moderately efficient in MPP tracking. Due to its simplicity it can be very easily integrated with a PV module which would serve the purpose of battery charge controller and no separate charge controller would be needed. The efficiency of the MPPT circuit is more than 95% and the system, with the buck converter, is 86% efficient.
