兩種PWM變換器無源軟開關方法的比較分析

摘要：無源軟開關由于使用元器件少，結構簡單，控制方便，成本低，效果理想再次引起了人們的關注。本文介紹了兩種典型PWM變換器無源軟開關的特性，并作了比較分析，指出了它們各自優點及適用場合。 敘詞：無源 軟開關 PWM變換器 Abstract：The research on passive soft switching being an interesting field again for several reasons, such as less component, simple structure, easy to control and lower cost. Brief characters of two typical kinds of passive soft switching are given, the differences between these two methods are compared and analyzed in detail, and their respective advantages and application are also indicated in this paper.
