| 摘 要： | 高频开关电源控制回路传统的方法是采用电压模式单闭环控制,这种控制方法响应较慢,也不能对功率器件进行实时电流限制。为了实现输出电压电流均可控,通常采用电流模式控制,常用电流模式控制有峰值电流控制法和平均电流控制法。本文对高频开关电源平均电流模式控制方案设计进行探讨。

| Abstract: | Voltage-mode single closed-loop control is the usual way to control loop in high-frequency switch power supply control,which is relatively slow in response and also cannot restrict power components from real-time current.Voltage-mode control is usually used to make both out-put voltage and current controllable and general voltage-mode control includes peak current control and average current control.This paper discusses design scheme for average current control in high-frequency switch power supply. |
