Abstract :
This paper presents a dynamic nonlinear model for Bidirectional Multi-Input DC-AC Converter and is used to meet the requirement of many Distributed Generation (DG) systems, such as Photovoltaic (PV) and Fuel Cell (FC) systems. The converter is analyzed step by step to show the principles of the operation in providing energy management based on duty cycle variations. The system capability in different operation conditions has been simulated. Dynamic analysis and control design of the bidirectional DC-AC converter is presented based on the steady state and small signal studies.
