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