CONTROL FOR AN INDUCTION-BASED AEROSOL DELIVERY DEVICE

摘要

An aerosol delivery device is provided that comprises an induction transmitter including a coil, and configured to generate an oscillating magnetic field, an induction receiver configured to generate heat when exposed to the oscillating magnetic field and thereby vaporize components of an aerosol precursor composition when in proximity of the induction receiver; and a control component configured to direct current to the induction transmitter to drive the induction transmitter to generate the oscillating magnetic field, the control component including a capacitor that with the coil forms a tank circuit, and the control component further including first and second switches that are alternately switchable to effect a zero voltage switching (ZVS) inverter topology in which the control component is configured to direct the current in cycles each of which includes a positive half in which the first and second switches are alternately switchable to charge the capacitor and direct current in a positive direction through the coil, and a negative half in which the first and second switches are alternately switchable to cause the capacitor to discharge and thereby direct current in a negative direction through the coil.
