最佳拓撲DC-DC變換電路的磁集成

摘要：　　本文針對目前開關變換器向“小、薄、輕”發展的趨勢[1]，介紹了CUK變換器中輸入電感和輸出電感相集成的三種方法，提出了耦合磁集成和解耦磁集成的概念，通過集成可達到減小變換器體積、減少磁芯數量和重量的目的，從而為開關變換器向“小、薄、輕”方向發展提供了一個行之有效的方法。 敘詞：CUK變換器 磁集成 耦合磁集成 解耦磁集成 Abstract：　　This paper introduces three kinds of integration methods of input inductance and output inductance in CUK switch convertor , following the trend of small,thin and light for the developing of the switch convertor at the present time. The concept of coupling integration and discoupling integration is presented. The purpose of minishing the volume of the convertor and decreasing the number of core and weight are reached, so the magnetics integration is an effect method for the development of switching convertor to small, thin and light. Keyword：CUK convertor, magnetics integration, coupling magnetics integration, discoupling magnetics integration.
