摘要： An adjustable inductor including a toroidal core defining a plurality of gaps, a compressible gap material positioned in the gaps, at least one winding wound on the core, a force-applying structure, and a film substantially covering the adjustable inductor. The force-applying structure is operable to apply a force to the core to adjust the gaps and thereby an inductance of the adjustable inductor. The film is configured to prevent movement of force-applying structure when above a predetermined temperature threshold, and allow movement of the force-applying structure when below the predetermined threshold.

摘要： Enhanced common mode current reduction in three-phase inductors, transformers, and motor drive systems. A motor drive system includes an iron core transformer, a common-mode transformer coupled to a three-phase motor, and a variable speed drive providing a three-phase power signal to drive the three-phase motor, and coupled to the iron core transformer and the common mode transformer. The system includes a DC bus having a DC bus midpoint. The common-mode transformer includes a toroidal ferrite core, a first choke winding, a second choke winding, a third choke winding, a first coupling winding collocated with the first choke winding, a second coupling winding collocated with the second choke winding, and a third coupling winding collocated with the third choke winding. The first, second, and third coupling windings are coupled in parallel to one another. The coupled windings couple a neutral point of the iron core transformer to the DC bus midpoint.

摘要： An alternating-current (AC) voltage regulator configured to receive an input voltage. The regulator including an AC/DC pulse-width modulated (PWM) power supply configured to receive the input voltage and output a direct-current (DC) signal isolated from the input voltage. The regulator including a control circuit configured to receive a portion of the input voltage, adjust an amplitude and a phase of the portion of the input voltage, and output the adjusted voltage. The regulator including an amplifier configured to receive, via an power input, the isolated DC signal; receive, via a first input, the adjusted voltage; receive a feedback loop from an amplifier output to a second input; and output, via the amplifier output, a differential signal. The regulator including an output configured to add the differential signal to the input voltage resulting in a regulated voltage, and output the regulated voltage.

摘要： The present disclosure provides descriptions of configurations for noise reducing and cooling enclosures and enclosure material. The noise reducing and cooling enclosures seal and passively acoustically quiet acoustic energy generated by one or more noise emitting devices within the enclosure, and dissipate heat generated by the devices through conduction by use of composite enclosure materials.
