摘要：

This paper presents an improved modeling and detailed analysis for determining the steady-state and transient performance of a high-performance ac/dc converter topology that can be utilized in high-frequency power distribution systems. The output voltage is regulated by controlling the turn on time of the anti-parallel semiconductor control switches. Both the steady-state and transient performance is explored in details. It is shown that the converter has almost unity power factor of close to 99% input current is almost sinusoidal with a total harmonic distortion of less than 2%, a conversion efficiency of close to 96% and very low inrush current of around 110% can be achieved, when appropriate circuit components are used. Based on predetermined value of the input current total harmonic distortion, consideration is given to the design of important circuit components.
