The Design and Simulation of Single-phase Boost Power Factor Corrector Circuit

根据Boost变换器的特点和要求,设计了一个具体、实用的带有源功率因数校正(APFC)功能的开关电源电路,并运用仿真软件MATLAB/Simulink,建立Boost主电路和控制电路的仿真模型.仿真结果证明:平均电流控制的单相Boost型APFC电路,完全能够达到整流、高输入功率因数、升压、稳压、低纹波的目标.

Basing on the characteristics and requirements of Boost converter, we design a practical switching power circuit with the function of APFC, and establish simulation model of active power factor corector based on Matlab/Simulink. Simulation results proved that the Boost APFC rectifier can achieve good performance of high power factor, regulator and low ripple.
