资料介绍

PFC电路是家用变频空调室外机控制器基本的单元电路之一,根据控制电路的不同,分为无源和有源PFC两大类,有源PFC电路因其优点多而得到很好的发展。目前,有源PFC的整流滤波电路通常用少量大容值的铝电解电容组成,存在成本高和寿命短的问题。本论文介绍一种新的有源PFC高压整流滤波电路,它由多数量小容值铝电解电容并联组成,辅以电流均流化设计,有效降低电容的ESR值,减小电容的发热,提升控制器寿命。

PFC circuit is one of the basic unit circuits in the outdoor machine controller of household inverter air con-ditioner. According to the different control circuits, it can be divided into two types, passive PFC and active PFC. Ac-tive PFC is developed well because of its advantages. Currently, active PFC rectifier filter circuit is usually constituted by small amount of large capacitance aluminum electrolytic capacitors. It has the problems of high cost and short life. This paper introduces a new active PFC high voltage rectifier filter circuit, which consists of many small capacitance electrolytic capacitors connected in parallel with current average design. By this way, we can effectively reduce the ESR values of capacitors and the capacita...
