Title (EN) LOAD POWER CONTROL METHOD USING A PHASE CONTROL SYSTEM, AND DEVICE THEREFOR
(FR) PROCEDE DE COMMANDE DE PUISSANCE D'UNE CHARGE VIA UN SYSTEME A REGLAGE DE PHASE ET DISPOSITIF DE MISE EN OEUVRE DE CE PROCEDE
Abstract:
(EN) A method for controlling the power of a load (1) powered from a source of AC voltage U having a period T using a phase control system, wherein, for a predetermined set power, a sequence of an integer p of elements, where p is greater than 1, is periodically delivered to said load (1), each element, numbered i, of the sequence being characterised by an integer ni with a half-period T/2 during which the AC voltage U is switched according to a series of different phase angles $g(a)i from $g(a)1 to $g(a)n corresponding to respective durations ti from t1 to tn during which the load (1) is cut off from the power supply. The phase angles $g(a)i of element i and $g(a)i+1 of element i+1 have similar repetitive values so that the mean current is zero over a complete cycle.
(FR) Procédé de commande de la puissance d'une charge (1) alimentée par une source de tension alternative U de période T via un système à réglage de phase, dans lequel, pour une puissance de consigne préalablement fixée, on délivre successivement à ladite charge (1), périodiquement une séquence d'un nombre entier p d'éléments, p étant supérieur à un, chaque élément, de numéro i, de la séquence étant caractérisé par un nombre entier ni de demi-période T/2 pendant lesquelles la tension alternative U est découpée selon des angles de phase consécutifs différents $g(a)i allant de $g(a)1 à $(a)n correspondant respectivement à des durées ti allant de t1 à tn pendant laquelle la charge (1) n'est pas alimentée, les angles de phases $(a)i de l'élément i et $(a)i+1 de l'élément i+1 ayant des valeurs semblables répétitives de telle sorte que le courant moyen soit nul sur un cycle complet.
