Title:
THYRISTOR COMMUTATION CIRCUIT
Document Type and Number:
Japanese Patent JPS62217854
Kind Code:
A
Abstract:
A commutating circuit in combination with a snubber circuit are employed to switch a thyristor from a conducting state to a non-conducting state. The snubber circuit is connected across the cathode and anode of the thyristor to absorb system energy when the thyristor is switched. The commutating circuit is coupled in series with the cathode of the thyristor by means of a current transformer for increasing the cathode resistance, causing the cathode current to immediately transfer to the gate.
