In this paper the investigation results of a boost Flyback converter, which is used in a micro-inverter, are presented. The efficiency characteristics of the converter at various carrier frequencies and output loads were investigated. An alternative circuit diagram solution which is less complex in structure and has fever components but has the same properties as the classic circuit scheme is proposed for the converter. The proposed Flyback converter is less expensive. Its efficiency is 2-3% higher than the classic Flyback converter when the converter output power is less than 95 W. [ABSTRACT FROM AUTHOR]
