摘要
研究表明，在脉宽调制(PWM) dc - dc变换器、dc - ac逆变器或放大器以及输入电流整形dc - dc变换器中，由于开关作用引起的非线性通常可以方便地限制在称为PWM开关的三端结构中。PWM开关是一种静态非线性，其电路模型可以很容易地推导出与扰动频率相关的谐波频率。变换器分析现在可以用类似于普通晶体管电路分析的方法来进行，即非线性三端器件被其电路模型所取代。该模型的一阶近似得到小信号模型。
It is shown that nonlinearity due to the switching action in pulse width-modulated (PWM) DC-to-DC converters, DC-to-AC inverters or amplifiers, and input-current-shaping DC-to-DC converters can often conveniently be confined to a three-terminal structure referred to as the PWM switch. the PWM switch represents a static nonlinearity for which circuit models can easily be derived for frequencies harmonically related to the frequency of perturbation. Converter analysis can now be approached in an analogous way to ordinary transistor circuit analysis whereby the nonlinear three-terminal device is replaced by its circuit model. A first-order approximation of the model results in the small-signal model.<>
