摘要
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、提高功率因数的有效方法.论述了单相功率因数校正APFC的原理和方法,通过对Boost型滞环控制的DC-DC变换器采用Matlab进行仿真,获得最后校正的功率因数结果,说明这种PFC方案的确能获得良好的效果,适用于多种场合.
The wide application of conventional AC-DC converter has brought about significant harmonic pollution to electric power system. Active Power Factor Correction technology is an effective method to rest rain harmonic current and to increase power factor. APFC converter is composed of a main circuit and a control circuit. The theorem and method of active power factor of APFC are introduced in this paper,and the simulation experiment got a good result by using Matlab towards DC-DC Boost circuit with method of hysteresis control.
