The induction heating source is based on the Joule effect, which is that a driver will induce an electrical current, producing the motion of electrons due to the kinetic energy stored in these, resulting in heat shock that experience between them. The high-frequency electromagnetic waves are manipulated by a PWM is to generate a pulse train that varies its width. Our input power is 1000 watts, with a voltage of 110V and a current of 9.09A. We also use copper tube of 0.003 m for the coil surrounding the material to be heated.
