Induction Heating System Topology Review[/caption]
All induction heating systhems are developed using electromagnetic induction which was first discovered by Michael Faraday in 1831. Electromagnetic induction refers to the phenomenon by which electric current is generated in a closed circuit by the fluctuation of current in another circuit placed next to it. The basic principle of induction heating, which is an applied form of Faraday’s discovery, is the fact that AC current flowing through a circuit affects the magnetic movement of a secondary circuit located near it. The fluctuation of current inside the primary circuit
provided the answer as to how the mysterious current is generated in the neighboring secondary circuit. Faraday’s discovery led to the development of electric motors, generators, transformers, and wireless communications devices. Its application, however, has not been flawless. Heat loss, which occurs during the induction heating process, was a major headache undermining the overall functionality of a system. Researchers sought to minimize heat loss by laminating the magnetic frames placed inside the motor or transformer. Faraday’s Law was followed by a series of more advanced discoveries such as Lentz’s Law. This law explains the fact that inductive current flows inverse to the direction of changes in induction magnetic movement.
