International Classification:

H02J 50/10
H01F 38/18
H01F 27/28

Abstract:

One or more techniques and/or systems described herein provide a power coupling device, such as may be used to transfer power between a stator and a rotor. The power coupling device includes a support structure defining an opening. The power coupling device includes a core element including a ferrite material. The core element is received within the opening of the support structure. The core element defines a core channel. The power coupling device includes an inductive element that is received within the core channel. The power coupling device includes an attachment structure removably attached to the support structure. The attachment structure attaches the core element to the support structure. The core element is disposed between the support structure and the attachment structure.

Abstract:

An apparatus includes an RF power amplifier with a controller and an impedance matching network. The RF power amplifier is configured to drive a load in electrical communication with the RF power amplifier. The impedance matching network is located electrically between the RF power amplifier and the load. The impedance matching network is configured to match an output impedance of the RF power amplifier and an impedance of the load. The impedance matching network includes a set of fixed value impedance matching circuits configured to provide different discrete values. The RF amplifier includes a variable DC power supply powering RF transistors to result in a variable output impedance for the amplifier. The controller selects an impedance matching circuit of the capacitor presets and/or the right setting for the variable DC supply that result in minimum reflected power to match the output impedance of the amplifier to the output load impedance.
