Abstract
PURPOSE: To simplify the constitution by using a make-and-brake element, which changes to any one side either a power source and a current transformer having two primary windings or the primary winding of the current transformer supplying current from the power source.
CONSTITUTION: When the changing switch 20 is closed, the changing switch 22 is open, GTO thrystor is off, then a constant current flows to the primary winding of a current transformer 18, magnetic flux of the current transformer 18 is saturated, the secondary current of the current transformer is maintained in the zero condition. When the changing switch 22 is closed and the changing switch 20 is open, plus pulse voltage is induced on the secondary side of the current transformer 18, GTO thyristor 28 is turned off. Next, when the changing switch 20 is closed, minus pulse voltage is induced on the secondary side of the current transformer 18 and GTO thyristor 28 is turned off.
