对于大多数实际电源应用，功率因数校正（PFC）变换器通常工作在稳定的连续导通模式（CCM）下，但只要这些变换器工作在振荡状态下，输入电流就会发生畸变。这种失真通常表现为一个线路周期内的本地振荡。通常，在一般脉宽调制（GPWM）控制下的Zeta PFC转换器具有高性能，并且需要具有较少外部元件的简单控制电路。然而，由于GPWM控制器的大信号非线性，其PFC变换器的输入电流畸变的动态分析和建模仍然是空白。在本文中，一个大信号平均SPICE模型推导出捕捉输入电流和输出电压的时域波形。提出了一种适用于CCM模式下PFC变换器的功率平衡方法，该方法利用傅里叶级数展开法预测变换器的稳态值。根据所提出的模型和不平衡功率传输模式，分析了失真行为。实验结果验证了所提出的方法。
For most actual power applications, power-factor correction (PFC) converters usually operate in the stable continuous conduction mode (CCM), but input current distortion will occur as long as these converters operate in oscillatory condition. This distortion usually manifests itself as a local oscillation within one line cycle. Typically, a Zeta PFC converter under the general pulse-width modulated (GPWM) control possesses high performance, and requires simpler control circuitry with fewer external components. However, due to the large-signal nonlinearity of the GPWM controller, the dynamic analysis and modeling of the input current distortion in its PFC converters remains vacant. In this paper, a large-signal average SPICE model is derived to capture the time-domain waveforms of the input current and output voltage. A power-balance approach for the PFC converter operating in CCM is developed, which can predict the steady-state values of the converters by using the Fourier series expansion. Analysis of the distortion behavior is provided in terms of the proposed model and the unbalanced power transfer mode. Experimental results are presented to verify the proposed method.
