  • Publication number: 20240074007
    Abstract: Provided are an electromagnetic heating device, a noise suppression method, a heating control system, and a storage medium, which relate to the field of electromagnetic heating technologies. The noise suppression method includes: in response to determining that any two adjacent heating modules of the electromagnetic heating device operate successively, obtaining a start operating frequency of the last-started heating module of the two adjacent heating modules; and adjusting an operating frequency of the first-started heating module of the two adjacent heating modules based on the start operating frequency of the last-started heating module, to allow the two adjacent heating modules to operate synchronously at a same operating frequency when the last-started heating module starts operating.
