Title:
CONTACTLESS RELAY
Document Type and Number:
Japanese Patent JPS5518197
Kind Code:
A
Abstract:
Solid state relay with a full-wave rectifier bridge having d-c output terminals, a thyristor, the anode and cathode of which being respectively connected to the output terminals of the rectifier bridge, a first and a second transistor, the load circuits of which being shunted across the gate-cathode path of the thyristor, the control terminal of the first transistor being connected to a first and a second resistor, the first resistor being, in turn, connected to the anode of the thyristor, and the second resistor being, in turn, connected to the cathode of the thyristor, the control terminal of the second transistor being connected to a third resistor and to a control transistor, the third resistor being, in turn, connected to the anode of the thyristor, and the control transistor being connected to the cathode of the thyristor, including a Zener diode connected in series with the first resistor.
