摘要
介绍了一种应用于某高压变电站直流控制屏的稳压电源。它采用在线式直流斩波稳压的形式工作,用PWM控制来达到所需的稳压精度。本电源较目前的在线式UPS系统具有更高的连续供电可靠性,而且结构简单,价格低廉,适合作为对供电可靠性要求很高的控制电源及应急事故电源等。
Introduces a kind of voltage stabilizing power, which is applied on the directcurrent control board of some high voltage transformer substation. It works by the online type direct current chopped wave voltage stabilizing way and attains the voltage stabilizing precision by the control of PWM. This power is more reliable than the online type UPS continuous power supply that is now popular. Its construction is simple and it is cheap. Such power can be used to be control power and emergency power which need high reliability during power supply.
