Abstract

L'invention concerne les circuits électriques de commande de lampes à décharge. Elle se rapporte à un circuit qui comprend deux bornes 1, 2 destinées à être reliées à une source de tension sinusoïdale, deux bornes 3, 4 destinées à être reliées à une lampe à décharge, une impédance 5 de charge, un dispositif 6 de démarrage et un dispositif 7 de déconnexion du dispositif de démarrage lorsqu'une décharge a été amorcée. Le dispositif 7 fonctionne lorsqu'une forme d'onde sinusoïdale prend une forme rectangulaire. Application à la commande des circuits d'amorçage des lampes à décharge.
