前言本文介绍的稳压变压器,实际上是铁磁谐振稳压电路的另一种形式。它不仅结构简单,对电网电压变化有不大于1%的稳定度,而且相当于一个低通滤波器,对脉冲干扰有良好的衰减作用。它本身能限制负载的过流和短路,此时输出电压呈下垂特性,输入功率也相应减小,不存在过压问题,不需要任何保护线路,元件少,价格低廉,可靠性高,平均失效间隔时间长达20至30万小时。因此,在计算机及其它电子控制设备中可广泛应用。稳压变压器实际上相当一个变压多组输出的交流稳压器,特别是在电网波动严重的环境 Preface This article describes the regulator transformer, in fact, another form of ferroresonance regulator circuit. It not only has the advantages of simple structure, no more than 1% stability to the voltage change of the power grid and is equivalent to a low-pass filter, which has a good attenuation effect on impulsive interference. It can limit the load over-current and short-circuit, the output voltage is drooping, the input power is reduced accordingly, there is no overvoltage problem, no protection circuit, less components, low cost, high reliability and average failure Interval of up to 20 to 300,000 hours. Therefore, in computers and other electronic control devices can be widely used. Regulated transformer is actually quite a transformers multi-group output AC voltage regulator, especially in severe fluctuations in the power grid environment
