Abstract

PURPOSE:To ensure the conduction of a thyristor by providing a resistance element, which has a prescribed resistance value, between the gate and the cathode of the photo thyristor or between the anode and the cathode of the photo thyristor and flowing the current for reverse bias between the anode and the cathode to this element. CONSTITUTION:Resistance element 5 is connected between the gate and the cathode of photo thyristor PThy1 which constitutes a solid relay circuit with zero cross, and resistance element 6 is connected between the anode and the cathode as required. At this time, the maximum value of the resistance value of elements 5 and 6 is set to a range where pulling-out effects of the leak current of the thyristor and the displacement current dependent upon dv/dt from the gate are obtained for element 5 and the transistor constituting the circuit is made conductive surely for element 6. Next, the minimum value of element 5 is determined according to the ignition characteristic of the thyristor, and the minimum value of element 6 is set according to the ignition current minimum value of the two-way gate control semiconductor switch constituting the circuit.
