Abstract
A resonant circuit for an aerosol generating system includes an inductive element for inductively heating a susceptor arrangement to heat an aerosol generating material to thereby generate an aerosol. The circuit also includes a switching arrangement that, in use, alternates between a first state and a second state to enable a varying current to be generated from a DC voltage supply and flow through the inductive element to cause inductive heating of the susceptor arrangement. The switching arrangement is configured to alternate between the first state and the second state in response to voltage oscillations within the resonant circuit which operate at a resonant frequency of the resonant circuit, whereby the varying current is maintained at the resonant frequency of the resonant circuit.
