摘要: A new half bridge converter without DC offset of magnetizing current is proposed. The ZVS operation proposed maintained by only reflected load because it doesnpsilat have as the duty changes. Therefore has high efficiency and power density especially when a wide input range. operational principle, large signal modeling analysis are presented. Experimental results demonstrate that can achieve range significant improvement in for 280 W (12 V, 23.3 A) prototype converter.
