Tapped Inductor SEPIC Converter for Photovoltaic System under Fast Varying Solar Irradiation and Load Voltage
Abstract
Under fast varying irradiance and load resistance a fast converging MPPT system is required to ensure the PV system response rapidly with minimum power losses. The current and voltage are sensed by the MPPT controller. This controller is used to regulate the duty cycle of the dc-dc converter. The system simply consists of a dc-dc converter which is connected in between PV module and the load. SEPIC converter is suited for alternative energy generation applications. An inverter is connected at the output of dc-dc converter. In order to step up the low voltage of solar panel a tapped inductor SEPIC converter is introduced. This converter has the advantages of continuous input current which can be helpful in attaining accurate tracking of maximum power point of solar panel. Further increase in voltage gain obtained by applying a charge pump. Therefore, features of continuous input current and as a result of lower input voltage ripple across photovoltaic can be helpful, assisting the controller tracking the maximum power point with greater accuracy.
