要約(日本語): A series-parallel asymmetrical half-bridge converters with high efficiency has been proposed. The proposed circuit has series connection of asymmetrical half-bridge converters (ASY-HBs) in the primary side, and parallel connection of ASY-HBs in the secondary side. Because of the series connection in the primary side, low-voltage MOSFETs with low on-resistances can be used. Also, the conduction loss in the secondary side can be decreased by parallel connection of ASY-HBs. Therefore, it has been shown that the efficiency of the proposed circuit can be improved when the number of ASY-HBs are increased.
