本文介绍稳定交流电源的某些方法;特别讨论关于从变化±20%的50赫电源产生固定标称输出值的问题.这个方法把半导体开关元件都当作所说的同步开关使用,已用过的和正在使用的稳压器有各种形式.这些包括驱动变压器,分流变换开关变压器和铁磁共振变压器.这些只具有实用的优点,它们在速度精确性和低成本方面不可能与这里讨论的稳压器形式相比. This article describes some of the ways to stabilize AC power, and in particular discusses the problem of producing a fixed nominal output value from a 50 Hz power supply varying by ± 20%. This approach uses the semiconductor switching elements as the synchronous switch, There are various forms of voltage regulators that are in use, including drive transformers, shunt switching transformers, and ferroresonance transformers, which have only practical advantages that are not possible with the speed accuracy and low cost discussed here Regulator compared to the form.
