摘要
Boost变换是非纯阻抗输入型电路,存在功率因数低的缺点。针对Boost变换设计了主动式功率因数校正电路,并采用PSIM软件进行了电路建模和仿真。仿真结果表明:采用功率因数校正电路后的Boost变换电路的功率因数高、总谐波畸变率低。
The impedance of Boost converter circuit is non-resistive with the disadvantage of low power factor.The active power factor correction circuit for Boost converter was designed,and the model and simulation waveform of the circuit based on the PSIM software was given.The result of simulation shows that the power factor correction circuit of Boost converter can improve the power factor,and reduce the total harmonic.
