单相APFC变换器主电路的设计

Design of the Main Circuits of Single-phase APFC Converters

传统AC-DC变换器的广泛应用对电网产生了大量的谐波污染.有源功率因数校正技术(APFC)是抑制谐波电流、提高功率因数的行之有效的方法,近年来受到了越来越多的关注.APFC变换器由主电路和控制电路组成,采用经验设计法对单相APFC变换器的主电路进行了设计,给出了具体电路参数的计算.

The wide application of conventional AC-DC converters has brought about significant harmonic pollution to a power network.Active Power Factor Correction technology is an effective method to restrain harmonic current and to increase power factor,which has received more and more attention in recent years.APFC converter is composed of a main circuit and a control circuit,the main circuit of a single-phase APFC converter was designed with the experiential method and the calculation of the circuit parameters were given as well.
