Maximum Power Point Tracker Based Digital One Cycle Control Applied in PV Systems

The Photovoltaic energy shown an alternative to meet the growing energy demand and reduce dependence on fossil fuels. This paper makes an approach to the need to extract the maximum power of photovoltaic panels via algorithms, such as the constant voltage. It was also used a tracking algorithm based on temperature measurement, where it returns the value of the reference voltage when a temperature change occurs. To make the switching controller was used the one cycle control - OCC by presenting a higher speed of convergence, disturbance rejection of the source and no steady-state error. It was implemented in a DC-DC Boost converter to extract the maximum power of the panel and was observed that OCC is faster than PWM and the temperature algorithm was more efficient than a pure constant voltage method.
