摘要： A static voltage regulator consists of a booster transformer, a regulator transformer, an electronic switching system and a control system. The booster transformer includes a booster primary winding and a booster secondary winding. The booster secondary is provided in series with the input and output terminals of the regulator so as to produce an output voltage. The regulator transformer includes a regulator primary winding and a regulator secondary winding. The regulator primary is electrically coupled to the output. The electronic switching system is coupled between the regulator secondary and the booster primary for providing a voltage to the booster primary. The control system includes a voltage sensor for sensing a voltage at the input, and a gating system coupled to the switching system for switching the output voltage in response to changes in the sensed input voltage. The voltage regulator also includes a notch filter coupled to the booster transformer for reducing transients induced in the booster transformer when the output voltage is switched.

摘要： A static transfer switch for reducing ferroresonance in a load consisting of a first switch for connecting and disconnecting a primary power source to and from the load, and a second switch for connecting and disconnecting a secondary power source to and from the load. Each switch includes a snubber circuit connected across the respective switch. An attenuator, consisting of a resistor in series with a capacitor, is connected between the first and second switches and ground and suppresses series ferroresonance at the load by reducing the voltage applied to the load when both the first and second switches are open and power is applied to or removed from the load.
摘要翻译：一种用于降低负载中的铁磁谐振的静态转换开关，包括用于将主电源连接到负载和从负载断开的第一开关，以及用于将二次电源连接到负载和从负载断开的第二开关。每个开关包括连接在相应开关上的缓冲电路。由第一和第二开关串联的电阻器组成的衰减器被连接在第一和第二开关之间并接地，并且当第一和第二开关都断开时，通过减小施加到负载的电压来抑制负载下的串联铁磁共振，而功率是应用于或从负载中移除。
