Title (EN) PHASE ANGLE DETERMINATION OF AC SIGNALS
(FR) DÉTERMINATION DU DÉPHASAGE DE SIGNAUX CA
Abstract:
(EN) Methods and circuitry are disclosed to produce a first signal representative of the AC voltage signal and a second signal representative of an AC current signal. The first and second signals may be combined with a clock signal to produce a third signal. A phase angle between the AC voltage signal and the AC current signal may be determined based on a pulse count indicative of how many pulses occur in the third signal over a predetermined period of time.
(FR) La présente invention concerne des procédés et des circuits pour produire un premier signal représentatif du signal de tension CA et un deuxième signal représentatif d'un signal de courant CA. Les premier et deuxième signaux peuvent être combinés avec un signal d'horloge pour produire un troisième signal. Un déphasage entre le signal de tension CA et le signal de courant CA peut être déterminé sur la base d'un comptage des impulsions indiquant le nombre d'impulsions se produisant dans le troisième signal pendant une période de temps prédéterminée.
