Title
(EN) FULL CYCLE AC POWER CONTROL
(FR) COMMANDE D'ALIMENTATION ALTERNATIVE À CYCLE TOTAL
Abstract
(EN)
A method includes selectively applying full cycles of AC power to a load. The cycles may have first and second states such as full on and full off states. The cycles may be arranged in groups in a pattern. The pattern may have a length that is shorter than a perceptible response time of the load. Different patterns may be used for different power levels.
(FR)
L'invention concerne un procédé qui comprend l'application sélective de cycles totaux d'alimentation alternative à une charge. Les cycles peuvent présenter des premier et second états tels que des états maximal et minimal. Les cycles peuvent être agencés en groupes selon un motif. Le motif peut avoir une longueur plus courte que le temps de réponse perceptible de la charge. Différents motifs peuvent être utilisés pour des niveaux d'alimentation différents.
