Analysis and design of the two-transformer asymmetrical half-bridge converter

Two-transformer asymmetrical half-bridge converter allows duty cycle larger than 50% and hence has the merits of lower output rectifier stress and wider input voltage range. In this paper, detailed circuit operations of the converter are analyzed. A practical design procedure is then developed. Zero...

Summary:Two-transformer asymmetrical half-bridge converter allows duty cycle larger than 50% and hence has the merits of lower output rectifier stress and wider input voltage range. In this paper, detailed circuit operations of the converter are analyzed. A practical design procedure is then developed. Zero voltage switching (ZVS) conditions of power switches are quantitatively investigated. Experimental results obtained from a 24 V/10 A prototype operating at 200 kHz are presented.
