Abstract
Proposed by the present application are an aerosol-producing device and a control method therefor. The device comprises: an inductance coil for generating a changing magnetic field; a capacitor, which forms an LC oscillator with the inductance coil; and a susceptor, which is penetrated by the changing magnetic field to generate heat. A PFM inverter driving module drives the LC oscillator to oscillate so as to make the inductance coil generate the changing magnetic field, and comprises: a bridge circuit and a PFM controller, wherein the PFM controller outputs a PFM signal to the bridge circuit so as to drive the bridge circuit to turn on or off so as to make the LC oscillator oscillate.
