An aerosol delivery device is provided that includes a substrate (610) configured to carry an aerosol precursor composition, and a resonant transformer (1202) including a transmitter coupling device (302) and a resonant receiver coupling device (602) that is positioned in proximity to the substrate. The aerosol delivery device also includes a pulse width modulation (PWM) inverter (1204) configured to drive the resonant transformer. The PWM inverter includes a bridge circuit (1206) coupled to the transmitter coupling device, and a PWM controller (1208) embodied as an integrated circuit and configured to output a PWM signal to the bridge circuit configured to drive the transmitter coupling device to generate an oscillating magnetic field and induce an alternating voltage in the resonant receiver coupling device when exposed to the oscillating magnetic field. The alternating voltage causes the resonant receiver coupling device to generate heat and thereby vaporize components of the aerosol precursor composition. La presente invención refiere a un dispositivo de suministro de aerosol que incluye un sustrato configurado para portar una composición precursora de aerosol, y un transformador resonante que incluye un dispositivo de acoplamiento de transmisor configurado para interactuar con un dispositivo de acoplamiento de receptor resonante que se coloca cerca del sustrato recibido en un contenedor. El dispositivo de suministro de aerosol también incluye un inversor de modulación de ancho de pulso (PWM) configurado para impulsar el transformador resonante; el inversor de PWM está configurado para accionar el dispositivo de acoplamiento del transmisor para generar un campo magnético oscilante e inducir un voltaje alternante en el dispositivo de acoplamiento del receptor resonante cuando se expone al campo magnético oscilante. El voltaje alternante hace que el dispositivo de acoplamiento del receptor resonante genere calor y, de ese modo, vaporice los componentes de la composición precursora de aerosol.
