  • Patent number: 11335495
    Abstract: An Insulated Core Transformer (ICT) high voltage DC power supply is disclosed. The power supply comprises a plurality of printed circuit boards, each comprising a secondary winding and a voltage doubler circuit. These voltage doubler circuits are arranged in series. The stacked printed circuit boards are surrounded by a plurality of grading rings. The last grading ring is electrically connected to the output voltage. High voltage resistors are then disposed between adjacent grading rings to form a voltage divider. The voltage of the first grading ring may be used as part of a feedback system to regulate the output of the AC power supply. By disposing the high voltage resistors on the grading rings, a more uniform voltage gradient may be created.

  • Patent number: 8971002
    Abstract: A system and method for providing isolated power to the gate driving circuits used in solid state switching devices is disclosed. Rather than using expensive isolated AC/DC power supplies, an isolation transformer is used to provide isolated AC voltage. In one embodiment, the primary winding of the isolation transformer is disposed across an independent AC source. In another embodiment, the primary winding of the isolation transformer is disposed across two phases of the AC power line. Isolated AC voltage is then generated across the secondary winding of the isolation transformer. This isolated AC voltage is then used by a non-isolated DC power supply, which generates the power for the gate driving circuit.

  • Publication number: 20140127394
    Abstract: Methods of reducing glitch rates within an ion implanter are described. In one embodiment, a plasma-assisted conditioning is performed, wherein the bias voltage to the extraction electrodes is modified so as to inhibit the formation of an ion beam. The power supplied to the plasma generator in the ion source is increased, thereby creating a high density plasma, which is not extracted by the extraction electrodes. This plasma extends from the arc chamber through the extraction aperture. Energetic ions then condition the extraction electrodes. In another embodiment, a plasma-assisted cleaning is performed. In this mode, the extraction voltage applied to the arc chamber body is modulated between two voltages so as to clean both the extraction electrodes and the faceplate of the arc chamber body.

  • Patent number: 8604449
    Abstract: An ion implantation system and method are disclosed in which glitches in voltage are minimized by modifications to the power system of the implanter. These power supply modifications include faster response time, output filtering, improved glitch detection and removal of voltage blanking. By minimizing glitches, it is possible to produce solar cells with acceptable dose uniformity without having to pause the scan each time a voltage glitch is detected. For example, by shortening the duration of a voltage to about 20-40 milliseconds, dose uniformity within about 3% can be maintained.
