开关电源控制方法综述

Survey on Control Methods of Switching Power Supply

从占空比的实现方式和控制电路的检测信号2个角度对开关电源的控制方法进行分类研究,详细介绍基于后一种分类方式下的电压型、电流型、V2型等几种控制方式的工作原理、特点和适用场合。在此基础上简要介绍模糊控制和滑模变结构控制等现代控制方法的原理和特点。最后根据对偶原理,对恒流源控制方法进行分类,并简述单环控制恒流源的工作原理。

The control methods of switching power supply are classified in realization of duty ratio and in detection signal of control circuit. The working principles, characteristics and applications are described in details for the control methods of voltage, current and V^2 types based on the second classification. Further briefed are the principles and characteristics of modem control methods of fuzzy control and sliding mode contrtrol, In the end the control methods of constant-current power supply are classified according to the coupling principle. The working principle of single-loop controlled switching power supply with constant current is introduced in brief.
