Abstract: An apparatus, method and computer program can include generating, obtaining or receiving a first control signal, at or from a control module, for switching elements of a first switching arrangement, wherein the control module implements a heating phase operation and a non-heating phase of operation of a first resonant circuit. The first resonant circuit includes one or more inductive elements and one or more capacitive elements, wherein the one or more inductive elements are for inductively heating a first susceptor arrangement to heat an aerosol generating material to thereby generate an aerosol. The first switching arrangement has a first state (in which a varying current is generated from a voltage supply and flows through the one or more inductive elements of the first resonant circuit) and a second state (in which the first switching arrangement is non-conducting).
