Abstract
PURPOSE: To measure turn-off time without applying reverse bias to a thyristor by connecting a d.c. reactor to a d. c. power supply, flowing its d. c. excitation current to the thyristor to be measured via capacitor and utilizing the fact that the current is cut off when the capacitor is charged to the designated voltage.
