ABSTRACT:
A microprocessor-based burner control apparatus includes an input stage adapted for controllably generating an input signal which is repetitively transitional between a first logic state and a second logic state. A synchronously controlled output stage includes a capacitor, a rectified source of alternating voltage and a microprocessor-switched transistor for controllably charging the capacitor during a half cycle of the alternating voltage having a first polarity. The capacitor is discharged during half cycles of the alternating voltage having a second polarity and the charging and discharging activity thereby actuates a load device. A programmable microprocessor is coupled to the input and output stages and is adapted to receive a synchronizing signal whereby the charging and discharging activity occurs in a predetermined relationship to the synchronizing signal. A method for controlling the operation of a combustible fuel burner is also disclosed.
