Abstract
PURPOSE: To improve reliability in control by making any form of control possible by exercising the control according to programmed control data obtained from a memory.
CONSTITUTION: Coil 2 and bilateral thyristor 3 are connected to commercial AC power supply 1, welded electrode 5 is coupled with coil 2, and the photo detector of photocoupler 6 is connected to thyristor 3. Then, a light emitting element constituting zero-cross point detector 7 is connected to power supply 1, and the data output of programmable controller 11 with a memory is led to the input of latch circuit 12; and the output of circuit 12 is supplied to variable-length shift register 13, the output of which is input to detector 7 via waveform shaping circuit 14. By a zero-cross detection signal from detector 7, clocks from oscillator 21 are counted by register 13 according to data in the memory of controller 11 and the operating angle to thyristor 3 of power supply 1 is determined by the output of register 13.
