多組變壓器在低壓大電流開關電源中應用的研究

摘要：本文介紹了一種低壓大電流開關電源采用的變壓器結構，并與傳統的一組變壓器結構進行了比較。以12V/1000A移相全橋ZVS開關電源的PSPICE仿真驗證了這種結構的優點。 敘詞：ZVS；移相全橋；PSPICE仿真 Abstract：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 in this paper, and compared with the structure of one transformer. Its merits of this structure are explored by PSPICE simulation of 12V/1000A power supply of shifting phase full bridge ZVS. Keyword：ZVS；shifting phase full bridge；PSPICE simulation
