zvs heating circuit

The principle of induction heating is a heating method that converts electrical energy into magnetic energy so that the heated steel body senses the magnetic energy and generates heat. That is, electrical energy is converted into magnetic energy and then into thermal energy. Electricity generates magnetism, and magnetism generates heat, which is Faraday's law of electromagnetic induction. When current passes through the inductor, that is, the copper coil, an alternating magnetic field will be generated. When a steel or iron workpiece is placed in the copper coil, alternating magnetic lines of force will be generated on the surface of the workpiece, and the part of the workpiece placed in the copper coil will Alternating currents, that is, eddy currents, are generated. The eddy currents cause the steel atoms and iron atoms inside the workpiece to move irregularly at high speeds. The atoms collide and rub against each other to generate heat energy, which has the effect of heating the workpiece, that is, converting electrical energy into magnetic energy. , a heating principle that causes the heated steel body to induce magnetic energy and generate heat.
