SIMULATION AND EVALUATION OF EFFICIENCY OF ACTIVE CLAMP DUAL FLYBACK INVERTER FOR PHOTOVOLTAIC SYSTEMS

摘要

Dual flyback inverter (DFBI) is one of the preferred topologies for isolated low cost low power photovoltaic (PV) applications. It converts PV cells DC voltage to output AC voltage using single power stage. It is important to understand loss distribution of DFBI be able to reach efficiency limits of this topology. This paper evaluates the efficiency of DFBI based on computer simulation results worked-out by Simetrix circuit simulator.
