Abstract:
A power control method using AC power, the method being capable of performing: low power control that passes only two portions of positive direction waves of each one-cycle sine wave of the AC power and only two portions of negative direction waves of each one-cycle sine wave of the AC power, which have voltage levels lower than a set reference voltage level, through a system; and high power control that does not pass only two portions of positive direction waves of each one-cycle sine wave of the AC power and only two portions of negative direction waves of each one-cycle sine wave of the AC power, which have voltage levels lower than a set reference voltage level, through the system.
