ELECTRICALLY HEATED AEROSOL GENERATING SYSTEM AND METHOD
First Claim
1. An electrically heated aerosol generating system for receiving an aerosol-forming substrate, the system comprising:
- at least one heating element for heating the substrate to form the aerosol; and
a power supply for supplying power to the at least one heating element, the power supply comprising;
a voltage source,at least two supercapacitors, andswitches between the voltage source and the at least two supercapacitors, the switches being arranged such that, during a charging mode, the supercapacitors are connected for charging by the voltage source and, during a heating mode, the supercapacitors are connected for discharging through the at least one heating element.

Abstract
An electrically heated aerosol generating system for receiving an aerosol-forming substrate includes at least one heating element for heating the substrate to form the aerosol and a power supply for supplying power to the at least one heating element. The power supply includes a voltage source, two or more supercapacitors, and switches between the voltage source and the two or more supercapacitors. The switches are arranged so that, during a charging mode, the supercapacitors are connected so as to be charged by the voltage source and, during a heating mode, the supercapacitors are connected so as to discharge through the at least one heating element.

10. A method of electrically heating an aerosol-forming substrate, the method comprising the steps of:
-
providing at least one heating element for heating the substrate to form the aerosol; providing a power supply for supplying power to the at least one heating element, the power supply comprising a voltage source, at least two supercapacitors, and switches between the voltage source and the at least two supercapacitors; during a charging mode, selectively operating the switches so that the at least two supercapacitors are connected for charging by the DC voltage source; and during a heating mode, selectively operating the switches so that the at least two supercapacitors are connected for discharging through the at least one heating element.
