Chapter 15 AC and DC Equivalent Circuit Modeling of the Discontinuous Conduction Mode 这一章我们关注discontinuous conduction mode (DCM)的小信号模型. 在DCM, Switch的平均电压和电流成正比, 满足欧姆定律, 因此可以用一个lossless resistor, Re(d)代替. Diode的平均电压和电流表现为功率源, 其功率=Re上的功...
So far, we have derived equivalent circuit models for dc-dc pulse-width modulation (PWM) converters operating in the continuous conduction mode. As illustrated in Fig. 10.1, the basic dc conversion property is modeled by an effective dc transformer, having a turns ratio equal to the conversion...
