摘要： A passive, current dependent inductivity (1) comprises a magnetic core (2), windings (3) and at least one bank air gap (4). A saturation region (5) made of magnetic material is arranged between the bank air gap (4) and the windings (3). A magnetic flux path (6) bifurcates into a first path (61) passing through the saturation region (5) and into a second path (62) passing through the bank air gap (4) and bypassing the saturation region (5). The magnetic resistance of the first path (61) is lower than the magnetic resistance of the second path (62) for winding currents below a first saturation current (7a) and whereby the magnetic resistance of the second path (62) is lower than the magnetic resistance of the first path (61) for winding currents above the first saturation current (7a) due to saturation of the saturation region.

摘要： Embodiments of a radio frequency (RF) amplification device having an RF amplification circuit and an amplifier control circuit operably associated with the RF amplification circuit are disclosed. The RF amplification circuit is configured to amplify an RF signal in accordance with a transfer function. The amplifier control circuit includes a closed-loop linearization circuit and a calibration circuit. The closed-loop linearization circuit is configured to be activated so that the transfer function defines a closed-loop response and inactive so that the transfer function defines an open-loop response. For example, the closed-loop linearization circuit may become inactive at small-signal power levels. Accordingly, the amplifier control circuit also includes a calibration circuit configured to reduce a difference between the open-loop response and the closed-loop response of the transfer function. In this manner, the performance of the RF amplification device is maintained while the closed-loop linearization circuit is inactive.

摘要： A ferroresonant transformer to produce an output voltage that has a substantially constant output voltage that is substantially free of harmonics includes a ferromagnetic core with a winding part and primary and secondary windings on that part. The core also includes a flux return part. Magnetic shunts magnetically couple some of the flux from the core between the primary and secondary windings to the flux return part. The core includes a region with a reduced cross-sectional area that constitutes an air gap to form a built-in inductor. The remainder of the core works with the secondary winding and a resonating capacitor to generate a substantially harmonic-free, constant-voltage output. The transformer may have one set of primary-secondary windings if it is to operate on single-phase alternating current, or it may have multiple sets if it is to operate on multi-phase alternating current.
