基于功率变换器的小信号模型，设计了一种适用于功率变换器应用的数字电流模式控制器。基于模型的控制律的推导导致所设计的控制器适用于三种基本类型的转换器：（i）升压;（ii）降压;和（iii）降压-升压转换器。所设计的数字电流模式控制器对参考信号的变化具有快速的电流响应，而没有在使用传统模拟型电流模式控制器的转换器应用中通常观察到的不稳定问题。仿真和实验结果表明，所设计的控制器的实用性。
Based on a small-signal model of the power converters, a digital current-mode controller for power converter applications is designed. The model-based derivation of the control law results in the designed controller being applicable to three basic types of converters; (i) boost; (ii) buck; and (iii) buck-boost converters. The designed digital current-mode controller exhibits a fast current response to changes in a reference signal without the instability problem normally observed in converter applications that use a conventional analog-type current-mode controller. Simulations and experiments are presented to show the usefulness of the designed controller.
