Abstract
A power control apparatus includes a voltage detection circuit configured to generate a voltage signal as an analog signal corresponding to a voltage value of AC power supplied from a commercial power supply to a predetermined load, and a current detection circuit configured to generate a current signal as an analog signal corresponding to a current value of the AC power. The power control apparatus further includes an A/D converter configured to convert each of the voltage signal and the current signal into a digital signal, a switch, a signal processor configured to control a switching operation of the switch based on a detection timing for the voltage value and a detection timing for the current value, and a controller configured to control supply of the AC power to the load.
