Abstract

This paper presents the development of an efficiency maximum power point tracking (MPPT) controller for a standalone photovoltaic (PV) system. An important component in the MPPT controller is the boost converter. The main objective of the study is to develop an efficient boost converter so as to achieve a cost effective MPPT controller. In the proposed boost converter design, a passive regenerative snubber circuit is included to absorb the energy of stray inductance so as to reduce the IGBT switching losses. The simulation results show that the proposed boost converter design gives an efficiency of 93% which is better than the conventional converter. A computer simulation model of the PV system based on MATLAB codes has been developed to evaluate the performance of the MPPT controller. The proposed MPPT controller is found to be better than the conventional MPPT controller in which it gives efficiencies of 94% for temperatures lower than 29 °C and 89% for temperatures higher than 29 °C.
