Hybrid Modeling and Simulation for the Boost Converter in Photovoltaic System

Abstract

Photovoltaic (PV) system is composed of several elements as solar cells, boost converter, inverter and load. Owing to the existence of converters, photovoltaic system is a hybrid system contains continuous dynamic and discrete dynamic. Traditionally, the power electronic converter is difficult to model. This paper illustrates the modeling method of hybrid system, especially finite automata model. Based on finite state machine (FSM), the hybrid modeling of boost converter is presented. Finally, provides a simulation environment for such combination between continuous time system and finite automata, which employs the simulink and stateflow from Matlab.
