A controller may measure resonance current of a working coil, measure driving voltage of a switching element included in an inverter circuit that supplies current to the working coil, and generates a phase margin pulse based on the resonance current and the driving voltage. The controller may compare the phase margin pulse with a switching signal and determine a driving state of the induction heating apparatus, and control driving of the working coil based on the driving state of the induction heating apparatus. Additionally, when it is determined that a driving frequency of the working coil is included in a capacitive area, the induction heating apparatus stops from operating, or a driving frequency of the working coil is set again.

A structure for wireless communication having a plurality of conductor layers, an insulator layer separating each of the conductor layers, and at least one connector connecting two of the conductor layers wherein an electrical resistance is reduced when an electrical signal is induced in the resonator at a predetermined frequency. The structure is capable of transmitting or receiving electrical energy and/or data at various near and far field magnetic coupling frequencies.

An induction oven for the sterilization of equipment is disclosed. The invention effectively reduces sterilization cycle times from 90 minutes to less than 30 minutes using dry heat. In addition to increased efficiency, the dry heat also avoids pitting and other forms of degradation of the materials being sterilized. The oven can be configured by the user to generate a resonance of a particular frequency to target the specific type of metal or other induction material being heated. Target induction materials include cast iron, stainless steel, brass, and graphite, for example. The oven includes a coil that generates the time-varying electromagnetic field using a two-dimensional spiral having a rectangular pattern. The spiral coil is formed on a printed circuit board. The oven is configured to receive a container for heating articles. The container includes a bin, e.g., aluminum, and transparent lid with a gasket therebetween to produce an airtight seal. The container can be used to both sterilize equipment as well as store the sterilized equipment without contamination.
