Adjuster for alternating voltage

Abstract

Abstract PURPOSE: To reduce the number of connections between the intermediate taps when the voltage adjusting transformer and the series transformer are respectively located in separate cabinet, by connecting the intermediate taps of the voltage adjusting transformer. CONSTITUTION: The intermediate taps for the secondary windings S 1 , S 2 of the transformers PT 1 , PT 2 of the voltage adjusting transformer TR 1 are directly connected. Further, the common connections 8 of the series transformer TR 2 of the switches SW 1 and SW 2 to select the taps is connected to one end of a primary winding P 3 of the series transformer TR 2 . Further, the common connections 7 of the series transformer TR 2 of the switches SW 3 , SW 4 are connected to another end of a primary winding P 3 of the series transformer TR 2 . Further, by suitably turning on and off the switches SW 1 WSW 4 , various amplitude of voltages are fed to a primary of the series transformer TR 2 and the secondary voltage according to the ratio of number of windings is fed to the input voltage.
