用滞环控制实现可编程交流电源设计

Design of Program mable AC Power Source Realized by Holding Ring Control

本文论述了用滞环控制实现的可编程交流电源的设计。该交流电源采用电压滞环控制的PWM技术,并结合高频变压器技术,不仅可以输出标准的正弦波电压,而且实现了任意波形的功率放大,响应速度快,失真小。该交流电源可以作为测试用交流电源,例如开关电源测试、电机测试等等。

In this paper,design of the programmable AC power source realized by holding ring control is presented.By using the voltage holding ring control and the technology of high fre-quency transformer,this AC power source,which has quick re-sponse and less distortion,can not only output standard sine wave voltage,but also realize power magnification of any wave.This kind of AC power source can be used for tests such as switching power test,electromotor test and so on.
