Definitions

  • control means detects a critical condition when the current or voltage exceeds a threshold value (V rof egu m, n ) and stops adjusting the frequency or the switch-on-time in response thereto.
  • the control means monitors the frequency or the switch-on-time of the half bridge and determines whether ignition has occurred in dependence upon the frequency after a predetermined time period.
  • V d is below the first lower threshold V ret - Deteclion at the end of the ignition phase (time period shorter than Time_out) then the circuit enters the run mode and applies a normal operating frequency to the switches Q l and Q2.

Abstract

On décrit un ballast électronique pour lampe, telle qu'une lampe à décharge gazeuse, de préférence une lampe fluorescente (LA), qui comprend un inverseur raccordé à une source de tension (Vbus) en courant continu; et un circuit de charge comportant la lampe (LA) et un circuit de résonance en série raccordé à l'inverseur. L'inverseur est formé de deux commutateurs (Q1, Q2) disposés en demi-pont et pouvant être commandés de manière alternée par un circuit de commande (1), au cours d'une phase d'allumage, de façon à augmenter leur temps de mise en marche (Ton) et à réduire ainsi la fréquence de commande. Le ballast se caractérise en ce que, dans les phases d'allumage, le circuit de commande (1) surveille un paramètre de sortie du demi-pont pour déterminer l'éventualité de l'allumage, par l'évaluation d'un paramètre de sortie ou d'un paramètre du demi-pont après un temps donné. Le circuit de commande (1) peut surveiller un courant ou une tension, ou une fréquence.
