Abstract
This paper deals with the design and experimental implementation of a maximum power point tracking (MPPT) for photovoltaic system, which is a DC-DC boost converter operating in continuous conduction mode (CCM). The converter is able to draw maximum power from the PV system for a given irradiation level by adjusting the duty cycle of converter. Analytical models are built for the PV system and converter on the basis of the data sheet of manufacturer and the principle of energy conservation. The control technique, implement with a single-chip microcontroller MC 56F8323EVM, is based on the P&O method. From the result obtained it can be concluded that the MPPT can increase the overall efficiency of the system for 94.5 % under different atmospheric condition. ฉ 2011 ICROS.
