Simulation of String Converter with Non Dissipative Current Diverter for Photovoltaic Applications

Abstract

Photovoltaic power generation is one of the major factor key to resolve energy demand. The proposed method is used to solve the string converter connection problem in photovoltaic (PV) power generation system, using non-dissipative string current diverter. The power generated by each PV module and the output voltage become unbalanced under inhomogeneous irradiation. A non-dissipative string current diverter is used to overcome this problem. String current diverter circuit is very easy to control and does not operate without inhomogeneous irradiation. Maximum power point tracking technique (MPPT) implemented in PV system to maximize the PV module output power where the latter depends on solar irradiance and temperature. Maximum power point tracking algorithm implemented on each dc-dc converter and to do so at the optimum efficiency.
