电流模式控制有效地消除了与输出滤波电感或储能电感相关的控制功能的相位滞后。几种类型的电流模式控制器在相位滞后特性方面略有不同，但它们都远远上级常用的PWM占空比控制器。不幸的是，业界对电流模式控制的巨大优势的认识和利用进展缓慢。这似乎有两个原因：（a）不存在非常适合于实现电流模式控制器的集成电路，以及（B）缺乏关于电流模式控制器的详细的、系统地组织的理论和实践信息。本文的目的是填补这一空白，提供了一个组织良好的有用的信息纲要，为设计工程师谁想要了解的电流模式控制的功率转换器的操作，并完成最佳设计。五种不同的控制方法被认为是，使用三种基本类型的调节矩形波功率转换器。
Current-mode control effectively eliminates the phase lag of the control function, associated with the output filter inductor or the energy-storage inductor. The several types of current-mode controllers differ slightly in their phase-lag characteristics, but they are all far superior to the commonly used PWM duty-ratio controllers. Unfortunately, industry has been slow to appreciate and exploit the considerable advantages of current-mode control. There seem to be two reasons for that: (a) the unavailability of integrated circuits which are well-suited to implementing current-mode controllers and (b) the lack of detailed, systematically organized, theoretical and practical information on current-mode controllers. The objective of this paper is to fill this gap by providing a well-organized compendium of useful information for the design engineer who wants to understand the operation of a current-mode-controlled power converter and to accomplish an optimal design. Five different control methods are considered, used with the three basic types of regulated rectangular-wave power converters.
