一种峰值电流模式Buck变换器的高频模型

In order to analyze the high-frequency behaviors of the peak current mode (PCM) Buck converter, a small-signal multifrequency model is proposed. The multifrequency model explains the influences from the sideband frequency components generated by the nonlinear PWM comparator. It can effectively reflect some features which cannot be shown by the conventional average model, such as the phase delay. I...
