TOPSwitch在功率因数校正电路中的应用

A Circuit of Power Factor Correction Based on TOPSwitch

单片开关电源由于其优异的性能在电气领域得到了广泛的应用,美国电源集成公司(PI公司)研制的第一代产品TOPSwitch系列除了在AC/DC电源变换器上得到广泛应用外,在功率因数校正上也有良好的表现。本文介绍了一种基于TOPSwitch的功率因数校正电路的工作原理、典型应用和制作实物的性能测试,取得了良好的效果。

Single-chip switching power supply has been widely applied in the electric field for its excellent performance, the first generation of products TOPSwitch series developed by United States Power Integrations Inc （PI＇s） are not only widely used in AC/DC power converters, but also a good performance in the power factor correction. This paper introduces the TOPSwitch-based power factor correction circuit works, typical applications and production of physical performance tests and achieved good results.
