ABSTRACT:
A solid state relay includes: an oscillator circuit responsive to a control signal for generating an a.c. signal; an isolation transformer having a primary winding which forms a part of the tank circuit of the oscillator circuit and a secondary winding; a rectifier responsive to the a.c. signal from the oscillator circuit for providing a d.c. drive signal; and a switch circuit responsive to the drive signal to open and close the relay.
