摘要

提出了一种带功率因数校正的正激变换器。本文的新颖之处在于将正激变换器与充谷电路相结合。正激变换器的辅助绕组包括在充谷变换器中。这种新型变换器具有高功率因数。本文将介绍该电路的设计、仿真和实验结果。该电路的另一个重要优点是减小了功率晶体管的应力。

A new forward based converter with power factor correction

The paper presents a forward converter with power factor correction. The novelty of the paper consists in a combination between a forward converter and a valley fill circuit. The auxiliary winding of forward converter is included in valley fill converter. The new converter has a high power factor. The paper will present the design, simulations and experimental results of the proposed circuit. Another important advantage of the proposed circuit is a reduced stress of the power transistor.
