Fuzzy Based Switched Boost Inverter for Solar PV Application

Abstract

Power electronics converters are required to interface solar PV panel to load or grid. Currently Z-source Inverter (ZSI) are in application. The ZSI due to their limitations need to be improved. In this paper Switched Boost Inverter (SBI) is proposed with modified PWM technique. SBI produces an output (both ac and dc) which can be either more or less than dc input voltage. In order to boost the voltage shoot-through state of inverter leg switches is allowed in this converter. In proposed SBI for solar application MPPT is also applied and fuzzy controller is applied to regulate output voltage. The proposed converter is validated through MATLAB/Simulink study and results.
