Abstract:
An aerosol delivery device is provided that includes an aerosol precursor composition and a quasi-resonant flyback converter configured to cause components of the aerosol precursor composition to vaporize to produce an aerosol. The quasi-resonant flyback converter includes a transformer including an induction transmitter and an induction receiver, a capacitor that with the induction transmitter forms a tank circuit. The quasi-resonant flyback converter also includes a transistor that is switchable in cycles to cause the induction transmitter to generate an oscillating magnetic field and induce an alternating voltage in the induction receiver when exposed to the oscillating magnetic field, the alternating voltage causing the induction receiver to generate heat and thereby vaporize components of the aerosol precursor composition.
