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.

Power coupling device

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.

Among other things, one or more techniques and/or systems are provided for varying a voltage applied to a radiation source of an imaging modality to vary an energy of emitted radiation. A power supply comprises at least two rectifiers, with a first rectifier being electrically separated from a second rectifier via a switching component. When the switching component is opened, the first and second rectifiers are effectively arranged in parallel, and when the switching component is closed, the first and second rectifiers are effectively arranged in series. The voltage applied by the power supply may be different based upon whether the rectifiers are arranged in parallel or in series, but the power output by the power supply may remain substantially constant regardless of the rectifier arrangement.
