单相功率因数校正PFC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，获得了最后校正的功率因数结果，说明这种PFC方案的能获得良好的效果，适用于多种场合。(The principle and method of single-phase PFC are introduced. By simulating the Boost hysteresis-controlled DC-DC converter with MATLAB, the final corrected PFC results are obtained. It shows that this PFC scheme can achieve good results and is suitable for many occasions.)
