Abstract

La présente invention concerne un circuit de commande IPL et un dispositif IPL comportant celui-ci. La présente invention est caractérisée en ce qu'un circuit de commande est utilisé pour charger jusqu'à trois fois une tension de crête d'alimentation commerciale lorsqu'il est utilisé dans une source d'alimentation commerciale ayant 110 V et jusqu'à deux fois la tension de crête d'alimentation commerciale lorsqu'il est utilisé dans la source d'alimentation commerciale ayant 220 V. Un circuit de commande IPL de la présente invention comprend : une unité d'opération de sélection de diode et de condensateur, dont une première borne est connectée à une première borne de la source d'alimentation commerciale, et qui fonctionne en tant que premier condensateur dans la source d'alimentation commerciale ayant une première tension et une première diode dans la source d'alimentation commerciale ayant une deuxième tension ; et une diode sensible à la tension d'entrée qui est connectée entre une deuxième borne de l'unité d'opération de sélection de diode et de condensateur et une deuxième borne de la source d'alimentation commerciale, et qui fonctionne en tant que diode dans la source d'alimentation commerciale ayant la première tension et fonctionne en tant que circuit ouvert ayant une résistance infinie dans la source d'alimentation commerciale ayant la deuxième tension.
