摘要

研究了一种功率因数校正的交直流升压变换器的电压控制和电流控制双环控制方法。传统的PI控制器由于其相对于快速变化的电流的缓慢动态而被用于负载电压调节。电流控制采用了一种更快的磁滞带电流控制器，易于物理实现。对功率因数校正升压变换器在不同负载条件下进行了仿真。给出了所得结果。实现了良好的功率因数。

Simulation of Power Factor Corrected AC-DC Boost Converter

A double loop control method, one for voltage control and the other for current control, for a power factor corrected ac-dc boost converter is studied in this paper. A classical PI controller is used for the load voltage regulation due to its slow dynamics with respect to fast changing current. A much faster hysteresis band current controller is used for the current control which has ease of physical implementation. The power factor corrected boost converter is simulated under different load conditions. The obtained results are presented. A good power factor is achieved.
