This paper presents a new control strategy for a single-stage flyback inverter, which consists of two flyback converters. The two converters alternately work in the proposed control scheme, which eliminate about 30% additional freewheeling power compared with a conventional differential control scheme. The control scheme is analyzed in detail. The 100-VA prototype with improved efficiency verifies the analysis.
