    Abstract: A method and apparatus for altering converter control as a function of the degree of unbalance in supply line voltages to substantially eliminate second harmonics on the supply lines caused by active control of the converter including identifying supply line peak amplitude values and using the peak values to identify potential second harmonics and then altering command values as a function of the potential second harmonic components.

    Abstract: A connector for an RF antenna for coupling the RF antenna to a device is formed from a base. A collar is provided for receiving and coupling to an RF antenna. A coupling structure extends from the base and engages the device to facilitate coupling of the antenna to the device. An antenna system is also formed from an RF antenna and a device to which the RF antenna couples and for which the RF antenna is used. The antenna system further includes a connector formed from a base, a collar for receiving and coupling to the RF antenna and a coupling structure that extends from the base and engages the device to facilitate coupling of the antenna to the device.

    Abstract: In accordance with certain embodiments, the present technique provides a reduced current field-oriented-control scheme. For example, the present technique provides a method of controlling an induction device in which a predetermined reduction factor is employed to reduce the flux-current vector of a field-oriented-control scheme. By reducing this vector, less current and less power are drawn by the induction device, in turn reducing resistive heating and stator core losses, for instance.
