    摘要： Examples disclosed herein relate to a switched coupled inductance phase shift mechanism. The phase shift mechanism includes a variable inductor element configured to toggle between a first inductance state and a second inductance state in response to a first control bit value, and a plurality of variable capacitor elements coupled to the variable inductor element and configured to toggle between a first capacitance state and a second capacitance state in response to a second control bit value. The variable inductor element and the variable capacitor elements collectively produce a first phase shift using the first inductance and capacitance states, and collectively produce a second phase shift using the second inductance and capacitance states, where a target phase shift is produced from a difference between the first and second phase shifts. Other examples disclosed herein relate to an antenna array and a method of phase shifting with switched coupled inductance.

    摘要： An adjustable inductance system includes a plurality of inductor modules coupled to a corresponding plurality of loads and a pool of at least one floating inductor module that may be coupled in parallel with any one of the plurality of inductor modules. A control circuit monitors the current drawn through the inductor module by the load. If current draw exceeds a threshold, the control circuit couples a floating inductor module to the load. Using the current drawn by the load, the control circuit determines an appropriate inductance value and determines an appropriate inductor configuration for the inductor module, the floating inductor module, or both the inductor module and the floating inductor module to achieve the determined inductance value. The control circuit causes switching elements to transition to a state or position to achieve the inductor configuration.

    摘要： Systems and implementations for inductance tuning systems that are configured to operate in a wide range of frequencies are provided herein. The subject matter described herein can in some embodiments include an inductance tuning system including at least one inductor connected to a first terminal, the at least one inductor comprising of a plurality of inductive elements that are substantially magnetically coupled to each other, wherein spacing between the inductive elements are substantially less than diameters of the windings. At least one capacitor can be connected between one or more of the plurality of inductive elements and a second terminal.

    摘要： An adjustable leakage inductance transformer includes a magnetic core, a primary side coil and a secondary side coil. The magnetic core includes a magnetic core column structure, which has a central column, a first outer column and a second outer column. The primary side coil is wound on the first outer column and the second outer column by a first primary side coil loop number and a second primary side coil loop number, respectively. The secondary side coil is wound on the first outer column and the second outer column by a first secondary side coil loop number and a second secondary side coil loop number, respectively, the first primary side coil loop number is not equal to the first secondary side coil loop number, and the second primary side coil loop number is not equal to the second secondary side coil loop number.
