Abstract
An apparatus for applying a magnetic pressure to a work piece includes an inductor configured to be disposed in proximity to the work piece and a controller electrically connected to the inductor and configured to control a supply of electrical power in order to output a first voltage over a selected frequency range to determine a frequency that provides a maximum current or a frequency that provides a current within a selected range of the maximum current to the inductor.
Claims7
A method for applying a magnetic pressure to a work piece, the method comprising:
- providing an input to a power supply to select a first output voltage using a controller, the power supply being coupled to an inductor that is disposed in proximity to the work piece;
- providing an input to the power supply to vary a frequency of the first output voltage over a selected frequency range using the controller;
- and
- determining a frequency that provides a maximum electrical current or a frequency that provides a current within a selected range of the maximum current at the first voltage to the inductor using the controller.
