Patent CA-2078911-A1 (CA)
Title: Interface circuit for low power drain microprocessor-based thermostat
Inventor: ADAMS JOHN T
IPC: F23N5/20
Filed: 1992-09-23
Abstract: A microprocessor-based power switching circuit responds to a common form of noise by disconnecting power from the controlled apparatus. The microprocessor provides an alternating voltage when power is to be provided, and the alternating voltage is converted by a detector circuit to a voltage close to ground which cuts off a transistor. When the transistor is cut off, an interface circuit places a thyristor which performs the actual power switching, into conduction. Noise on the base of the transistor can only drive it into conduction which then puts the thyristor into non-conduction.
