Resumen
The electronic devices used in heating systems thanks to the development of power electronics rapidly evolved to magnetic induction. Currently, Ecuador’s government is firmly committed to transform the country’s energy model. This will involve replacement of the classic gas-based heating systems for hot water by magnetic induction devices. The article presents a comparative study of different topologies of electronic circuits used in the induction heating process in the last 20 years. The evolution of electronic circuit’s magnetic induction is due to the technological breakthrough of soft switching devices. The existing topologies and their application in commercial electronic circuits demonstrate the growing interest in magnetic induction systems and the search for continuous improvement and increase in energy efficiency. The paper provides a detailed description of the different topologies used in the induction heating industry, and provides a comparison of the resonance frequencies, the powers of labor and the most relevant designs and dimensioning of electronic circuits for magnetic induction heating. The study pretends to serve as a theoretical basis for the selection and design of prototype domestic water heating systems by electromagnetic induction for domestic use.
