This paper deals with computer simulation of Dual Flyback Inverter (DFBI) for low cost photovoltaic applications. Efficiency of DFBI is investigated with standard IGBT transistors, CoolMOS MOSFETs and modern silicon carbide (SiC) JFETs. Critical parameters which are influencing efficiency of active clamp DFBI are described. DFBI can be used not only for active power generation but also for reactive power generation.
