Abstract
An aerosol delivery device is provided that includes a substrate configured to carry an aerosol precursor composition, and includes an induction transmitter, induction receiver and control component. The induction transmitter is configured to generate an oscillating magnetic field. The induction receiver is positioned in proximity to the substrate, and configured to generate heat when exposed to the oscillating magnetic field and thereby vaporize components of the aerosol precursor composition. The control component is configured to direct current to the induction transmitter to drive the induction transmitter to generate the oscillating magnetic field, with the control component being configured to direct the current according to a zero voltage switching (ZVS) inverter topology.
