多组变压器在低压大电流开关电源中应用的研究

Study on the Transformers Used in Power Supply of Low Voltage and High Current

介绍了一种低压大电流开关电源采用的变压器结构,并与传统的一组变压器结构进行了比较。以12V/1 000A移相全桥ZVS开关电源的PSPICE仿真验证了这种结构的优点。

In this paper, a structure of the transformers with the primaries in series and the secondaries in parallel used in power supply of low voltage and high current is introduced and compared with the strueture of one transformer. Its merits of this structure are explored by PSPICE simulation of 12 V/1 000 A power supply of shifting phase full bridge ZVS.
