摘要：
Under load tapchanging voltage regulators with source and load connections, series and shunt transformers, switching devices for causing selectable levels of electric power to flow in either direction between the series and shunt transformers, and tapchanger controls for sensing the voltage at said load connections and causing the switching devices to select proper electric power flows so as to maintain desired voltages at the load connections.
