摘要：
An aerosol-generating device is provided, including: an inductive heating arrangement to heat an aerosol-forming substrate and including: a susceptor arrangement heatable by penetration with a varying magnetic field, a first LC circuit having a resonance frequency and including a first inductor coil and capacitor, and a second LC circuit having the same resonance frequency and including a second inductor coil and capacitor; and a controller to drive the first and second circuits with respective first and second currents for generating respective first and second alternating magnetic fields for heating respective first and second portions of the susceptor, supply the first and currents with the resonance frequency a different frequency, respectively, supply the first current to the first circuit during a first phase to increase the first portion to a first operating temperature, and supply the first current with resonance frequency of the circuits during the first phase.
