摘　　要：针对输入隔离低压大电流输出的DC/DC变换器,提出一种高效、低功耗的磁集成结构.阐述了新型磁集成方案的基本原理和步骤,并将该磁集成结构应用于非对称半桥倍流同步整流电路设计.通过分析、比较集成磁元件与分立磁元件的电路设计过程和实验结果,验证了该磁集成方法的正确性和优越性.For the two-stage DC-DC converters of input with low-voltage and high-current out- put, a magnetic integration structure with low power dissipation is proposed. An asymmetrical half- bridge with current doubler and synchronous rectifier is chosen as an example to illustrate the princi- ples and the implementation procedure of the proposed integration scheme. Based on the perform- ance analysis and comparison between different designs of discrete magnetics and integrated magnet- ics, the result shows that the proposed structure is feasible and advantageous.
