ABSTRACT:
Alternating current electric power fed to a load is controlled to a target value using phase control. During a half cycle of the alternating current waveform, sampling of voltage and square calculation of the sampled value are repeated. During the remaining half cycle, average value calculation based on the result of the above calculation, root calculation and proportional calculation are implemented. Thus, the power control cycle is completed within one cycle of the alternating current waveform. By utilizing a plurality of sampling data, dropped data locating in a non-sampling period therebetween is obtained by interpolation. Sampling starts in synchronism with the energizing start-up phase.
