Induction Power Supplies

How does an induction power supply work?

An induction power supply generates the alternating current required to create a rapidly changing electromagnetic field, which induces heat in a conductive material.

1. The induction power supply takes an alternating current and converts it to high frequency alternating current through a rectifier that converts the incoming AC to DC.
2. The DC converted is then passed through an inverter, which switches the DC back into high frequency AC.
3. The high frequency AC flows through a copper induction coil, generating a rapidly changing magnetic field around the coil. When conductive material is placed inside or near the coil, the magnetic field induces eddy currents within the part.
4. The induced eddy currents flow through the workpiece, encountering resistance within the material. The amount of heat generated will depend on the power and frequency of the power supply, properties of the material, and coil design.
