摘要
开关电源的数字控制技术近年来得到了广泛的关注和快速的发展。开关电源数字控制器的核心是三个主要功能模块:模数转换器(ADC)、补偿器(COMP)和数字脉宽调制器(DPWM)。文章基于开关电源数字控制技术的发展现状,对这三个主要功能模块的不同实现方式进行了分类概述,分析了各种不同方式之间的区别,并给出了适用范围。
Digital control of switching mode power supply has been widely studied and fast developed in recent years. Digital controller of switching mode power supply contains three main function blocks： ADC （analog-to-digital converter）, COMP （digital compensation algorithm） and DPWM （digital-pulse-width-modulation）. Various implementations of these three function blocks are introduced and differences between them are analyzed. Also the application of different implementanons are Dven.
