The battery charging device comprises an integrator circuit having a D.C. power source; a voltage comparator; a solid state relay; a D.C. output circuit; a positive voltage feedback circuit; and a negative voltage feedback circuit. The integrator circuit receives A.C. power from an A.C. power source and provides an output to the voltage comparator. The voltage comparator, in turn, is connected so as to provide an output to the solid state relay. The solid state relay preferably includes a zero voltage closing circuit and provides an output to the D.C. output circuit. The D.C. output circuit is connected to a battery-to-be-charged and provides an output D.C. voltage thereto. The D.C. output circuit is also connected to and provides outputs to the negative and positive feedback circuits which, in turn, provide feedback to the voltage comparator. Preferably, optical coupling devices connect the output from the voltage comparator to the solid state relay, as well as the positive and negative feedback circuits to the voltage comparator.

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).
