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 S1, S2 of the transformers PT1, PT2 of the voltage adjusting transformer TR1 are directly connected. Further, the common connections 8 of the series transformer TR2 of the switches SW1 and SW2 to select the taps is connected to one end of a primary winding P3 of the series transformer TR2. Further, the common connections 7 of the series transformer TR2 of the switches SW3, SW4 are connected to another end of a primary winding P3 of the series transformer TR2. Further, by suitably turning on and off the switches SW1WSW4, various amplitude of voltages are fed to a primary of the series transformer TR2 and the secondary voltage according to the ratio of number of windings is fed to the input voltage.
