Closed Loop Zeta Converter with High Voltage Gain for Photovoltaic Application

Priya Thottan | Surya Natarajan [2]

Abstract: This topology consists of an extended high voltage gain converter along with a Zeta converter. The extended high voltage gain converter is operated with a fixed conversion gain whereas the zeta converter is controlled to do the maximum power point tracking (MPPT) which is an important advantage of this structure. The input current of the topology is continuous and its voltage gain is high without using any transformer. Reduction of the number of power electronic switches and costs are other most important benefits of the structure. Input of this topology is given by photovoltaic system with pertube and observe algorithm. The objective of this paper is to maintain the constant output voltage, irrespective of change in irradiance. Change in Irradiance, causes the change of output voltage from PV panel, which causes the duty cycle (D) to vary and duty cycle depends on both output voltage from PV module and reference voltage. Change in duty cycle makes the zeta converter to operate either in buck or boost mode
