用瞬时比较法研制交流稳压电源

Development AC Regulated Power Supplies With Instantaneous Comparison Law

瞬时比较法制作交流稳压电源的基本原理是采用输入电压与参考电压进行比较找出其波形的不足,对输入电压进行修补,通过改变控制电压以改善输入电压波形、稳定幅值,从而达到输出电压稳定的目的。其实质是利用小功率的控制电源得到大容量的稳定电压输出,使用该技术研制的交流稳压电源具有廉价、指标高、成本低、易控制的特点。

The basic principle of the instantaneous comparison test manufacture voltage-stabilized source＇s is to compare the input voltage with the referenced voltage to find out the shortcoming of the waveform and to mend the input, we can change the control voltage to make the input voltage waveform better and get a steady amplitude, thus achieves the output voltage stable goal.lts essence is uses the small control power source to obtain the large capacity stable output, this kind of A.C. stabilized voltage supply has the advantages over others in low price, high target and being easy to control.
