摘要
This paper presents the system analysis of a cascade boost-flyback back converter with high voltage conversion ratio to overcome the limit of conventional boost or buck-boost converter with narrow turn-off period. The proposed converter has wide turn-off period compared with the conventional boost converter. Thus the higher output voltage in the proposed converter can be realized The circuit configuration, principle operation, system analysis, and design consideration of the proposed converter are presented in detail. Finally, experiments conducted on a laboratory, prototype rated at 200W were presented to verify the effectiveness of the converter.
