一种交错并联数字化APFC电路的设计

Design of an interleaved type digital active power factor correction circuit

分析了一种交错并联数字化APFC电路。当电路工作于电流连续模式时,输入电流自动跟踪正弦输入电压。利用状态空间平均法建立电路的主功率模型,并对该电路的控制器进行设计,最后给出了MATLAB仿真结果。

An interleaved type digital APFC circuit is presented. The input current of this circuit automatically follows the sinusoidal line voltage when the circuit is operated in continuous current mode（CCM）. In the modeling of the circuit, the state-space averaging technique is used, and the regulator of the circuit is also designed. The simulation results are also given.
