Abstract: A dual solid state relay comprised of an input circuit, an optical coupler, a reference voltage circuit, a switch circuit, an SCR saturation circuit, a full wave bridge rectifier, a TRIAC driver circuit, an SCR driver circuit, a TRIAC slave circuit, an SCR slave circuit, a snobber circuit, and an output port. The TRIAC slave circuit and the SCR slave circuit are driven by the TRIAC driver circuit and the SCR driver circuit, respectively. The relay circuit is designed to employ additional TRIACs and SCRs in the event that the switching of very high currents and voltages becomes necessary. A further feature of the present invention is a SPDT switch which allows the user the opportunity of choosing which part of the relay circuit is utilized (TRIAC or SCR).

Abstract: A new GTO (gate turn-off) thyristor, especially one which can freely control the turn-on and turn-off of the SCR (silicon controlled rectifier) without affecting the features of the A.C. and D.C. function of the SCR i.e. the switching function of great current and high voltage which is impossible for transistor. The power consumption of the control circuits is very low and the power can be supplied by the input control source at the gate or by a separate source. With special design, this invention has little malfunction and is the best GTO thyristor in the world.
