Amplitude adjusting : ウィキペディア英語版 | Amplitude adjusting
The Amplitude adjusting (also referred to as Amplitude control) enables the power control of electric loads, which are operated with AC voltage. A representative application is the heating control of industrial high temperature furnaces. == Functionality ==
Contrary to the conventional phase angle or full wave control, during amplitude control only the Amplitude of the sinusoidal supply current is changed. The level of the amplitude only depends on the consumed power. The sinus oscillation does not change. Because current and voltage are in phase, only real power is taken from the mains for amplitude control. So the current consumption from the mains is considerably lower than the current consumption in case of phase-angle operation.
