The present disclosure provides a method for controlling a power of an electromagnetic cooking appliance and an electromagnetic cooking appliance. The electromagnetic cooking appliance includes a first coil disk and a second coil disk. Each of the first coil disk and the second coil disk corresponds to an independent resonance circuit. After obtaining a target power of the electromagnetic cooking appliance, a heating period of the electromagnetic cooking appliance is determined based on the target power, each heating period including at least one first heating time period and at least one second heating time period. The first coil disk is controlled to heat in the first heating time period, and the second coil disk to heat in the second heating time period, such that the first coil disk and the second coil disk are heated alternately to reduce an interference of harmonic current and voltage flicker.

A heating device includes a housing, a primary induction coil, a controller circuit, and a secondary induction coil. The housing is configured to retain a camera lens. The primary induction coil is positioned proximate the housing and configured to generate a magnetic field in response to receiving electrical power from a power supply. The controller circuit is in electrical contact with the primary induction coil and is configured to control the electrical power delivered to the primary induction coil. The secondary induction coil overlays the primary induction coil and is configured to receive the magnetic field from the primary induction coil and generate heat. The secondary induction coil heats the camera lens when the primary induction coil receives the electrical power.

The present technology is generally directed to multi-frequency controllers for inductive heating and associated systems and methods. In some embodiments, systems associated with the present technology are configured to precisely heat a module via a coil to a target temperature using oscillating, pulsed electrical signals associated with unique frequencies and/or capacitance values. Each unique frequency can correspond to heating the module to a particular depth, relative to an outer surface of the module. For example, a first pulsed electrical signal having a first frequency can heat the module to a first depth, and a second pulsed electrical signal having a second frequency can heat the module to a second depth different than the first depth. The system can further include a thermal sensor for measuring a temperature associated with at least one of the module or a fluid associated with the module. Based on the measured temperature, the system can adjust signal delivery parameters of the first and/or second electrical signals.
