Abstract
PURPOSE: To turn off a plurality of thyristors reliably by turning on a transistor connected in series with a series power source connected in parallel with each said thyristor thereby applying bias voltage on said thyristor.
CONSTITUTION: Gate signal or base signal is provided to the thyristors 2U+, 2V+... 2W- and transistors 6+, 6-. Thyristors 2U+, 2V+, 2W+ are phase shifted by 180° while the thyristors 2U+ and 2U-, 2W- are phase shifted by 120° and the signal having the width of 180° minus approx. 50 μs is inputed. Said 50 μs is the period when the transistor 6+ or 6- turns on, and the base signal is inputted to the transistor 6- when any one of the gate of the thyristors 2U+, 2V+, 2W+ distinguishes while it is inputted to the transistor 6+ when any one of the gate of the thyristors 2U-, 2V-, 2W- distinguishes.
