Fuzzy Logic Power Flow Control in divide Full Bridge Three-Port Converter

Abstract

On this work, the three-port converter derivative from the full-bridge converter is analysed and control. The full-bridge converter is made up of two parts, A and B. Each part contains two switches with independent input sources. The inputs drive the load through a transformer that boosts voltage and provides isolation. The controller is an important portion of the converter. It controls the pass of power between the three ports. The controller uses Fuzzy Logic Control to make decisions regarding the two control signals for each part. These decisions are based on the variance between the whole energy generated by the photovoltaic panel and the energy demand at the load. The proposed design is verified through MATLAB and Simulink.
