Abstract

PURPOSE:To easily attain the linear control by which an output proportional to the control input is obtained, by constituting a reference waveform generating circuit including a time function generator with a digital circuit. CONSTITUTION:A current/voltage converter 12 or the prescribed master/slave signal MS is supplid to a comparator 10. While the reference voltage equal to the prescribed signal MS is read out of a time function generator 8 when the specific trigger time (tx) elapses from the moment of a zero crossing of a power supply line PL. This digital data is converted into analog signals through a D/A converter 9 to be applied to the comparator 10. Then the output signal is delivered from the comparator 10 to drive a thyristor driving circuit 15. Thus a thyristor 1 conducts. In this case, the trigger time of the thyristor 1 is (tx) and the AC electric power to be supplied to a load 2 is identical with a value which is accurately proportional to the signal MS by the conduction of the thyristor 1. As a result, the linear control is carried out.
