Abstract

PURPOSE: To obtain a small-size solid relay circuit by connecting a fullwave rectifying circuit to the secondary side of an insulation-property transformer and controlling the rectifying current by the signal input to turn on and off a two-way semiconductor switch element.
CONSTITUTION: AC power source 1 is a commercial power source and is coupled in series with a circuit, where two-way semiconductor switch element 5 and primary side 8 of insulating transformrer 7 are connected in parallel, through load 2. Meanwhile, full-wave rectifying circuits 10...13 are connected to secondary side 9 of transformer 7, and the rectifying current is controlled by the presence and the absence of signal input, and element 5 is turned on and off by this rectifying current
