The goal of this paper is , by serial / parallel combination technique of two - transistos forward converters ( ttfcs ) , to keep the merits of the ttfc , and to overcome the shortages of it . the interleaving technique is adopted , while in combining ttfcs . the interleaving technique lowers the net ripple amplitude and raises the effective ripple frequency of the overall converter without increasing switching losses or device stresses
组合式双管正激变换器由双管正激变换器串并联构成，应用交错控制策略，在保留双管正激变换器功率开关管电压应力低和可靠性高的优点同时，克服了等效占空比小、副边二极管电压应力高、输出电流脉动大等缺点。
