Title
(EN) SOFT SWITCHING IN AN AEROSOL DELIVERY DEVICE
(FR) COMMUTATION DOUCE DANS UN DISPOSITIF DE DISTRIBUTION D’AÉROSOL
Abstract
(EN)
An aerosol delivery device is provided that includes a voltage regulator circuit, switching arrangement and processing circuitry. The voltage regulator circuit is coupled between a power source and a load including an aerosol production component, and configured to provide an output voltage in which voltage provided by the power source is regulated. The switching arrangement includes a first switch with first and second inputs coupled to respectively the voltage regulator circuit and ground, and an output coupled to the second switch; and a second switch coupled to and between the voltage regulator circuit and the load. The processing circuitry is configured to output a signal to cause the first switch to switchably connect the output voltage to the second switch and ground, and thereby cause the second switch to switchably connect and disconnect the output voltage to the aerosol production component to power the aerosol production component to produce aerosol.

L'invention concerne un dispositif de distribution d'aérosol qui comprend un circuit régulateur de tension, un agencement de commutation et un circuit de traitement. Le circuit régulateur de tension est couplé entre une source d'alimentation et une charge comprenant un composant de production d'aérosol, et conçu pour fournir une tension de sortie dans laquelle une tension fournie par la source d'alimentation est régulée. L'agencement de commutation comprend un premier commutateur ayant des première et seconde entrées couplées respectivement au circuit régulateur de tension et à la masse, et une sortie couplée au second commutateur ; et un second commutateur couplé à et entre le circuit régulateur de tension et la charge. Le circuit de traitement est conçu pour délivrer un signal pour amener le premier commutateur à connecter de manière commutable la tension de sortie au second commutateur et à la masse, et ainsi amener le second commutateur à connecter et déconnecter de manière commutable la tension de sortie au composant de production d'aérosol pour alimenter le composant de production d'aérosol pour qu’il produise un aérosol.
