  • Induction heating system output control based on induction heating device
    Publication number: 20060289493
    Abstract: In one exemplary embodiment, the induction heating system includes an induction heating power source. The induction heating power source is operable to identify an induction heating device coupled to the induction heating power source. The exemplary induction heating power source is operable to automatically limit power based on the identity of the induction heating device.

  • Induction heating system having multiple temperature input control
    Publication number: 20060289495
    Abstract: A system and method for inductively heating a work piece. The induction heating system is coupleable to a plurality of temperature feedback devices operable to provide a signal representative of work piece temperature. The induction heating system is operable to control the output of the induction heating system based on the plurality of signals representative of work piece temperature received from the plurality of temperature feedback devices.

  • Induction heating system and method of output power control
    Publication number: 20060289492
    Abstract: A system and method for inductively heating a work piece. The induction heating system is coupleable to at least one temperature feedback device. The temperature feedback device is disposed within the induction heating system to provide a signal representative of the temperature of an induction heating system component. The induction heating system is operable to control the output of the induction heating system based on the temperature of the induction heating system component to protect the component from heat damage.

  • Induction heating system with a flexible coil
    Patent number: 6346690
    Abstract: A method and apparatus for induction heating includes a power supply, and a controller, and an induction head. The induction head includes a flexible coiled, such as one formed with Litz wire. The head also includes a thermal insulator, for disposing between the head and the workpiece. The insulator reflects heat back to the workpiece, protecting the coil, but is transparent to inductive (E-M) energy. The power supply is a variable output frequency power supply, such as one having a resonant tank, to adapt to the inductance of the head.
