摘要
开关电源高频化、模块化、数字化的实现,将标志着开关电源控制技术的成熟,简述了当前开关电源的控制技术,从模拟控制和数字控制两个方面着手,介绍了PWM控制,PFM控制,PWM-PFM控制,基于单片机控制和基于DSP控制等五种控制方式的特点,并分析比较了它们的优缺点和应用范围.
The realization of high - frequency, modular, digital to Switching Power Supply marks the maturing of the technology of controlling Switching Power Supply. This article outlines the current control technology of Switching Power Supply, introduces the characteristics of the five control from the two aspects (analog control and digital control): the PWM control, PFM control, PWM- PFM control, based on Single - chip control and DSP - based control, analyzes and compares the excellences and weaknesses of these control in their applications.
