Abstract

PURPOSE: To enable to measure the turn-off time of the sample thyristor, by parallel connection of the active element having the switching capability of ON/OFF by itself to the diode in series connection with the sample thyristor.
CONSTITUTION: GTO31 or electrostatic induction type thyristor, or bipolar transistor 32 are connected in antiparallel to the diode 4. With the active element 31 or 32 ON, the inverse voltage is not fed to the diode 4 and with the active element 31 or 32 OFF, OFF voltage can be fed to the sample thyristor. Accordingly, even with the difference among thyristors to be tested for the turn-off time, the turn-off time can be measured without replacing the diode 4.
