摘要： An apparatus and corresponding systems and methods for managing electric power, particularly a transformer system and method, and more specifically a transformer for direct current. An example apparatus includes a chamber configured to contain plasma. The apparatus includes input electrodes disposed at least partially within the chamber, and configured to receive a first direct current input into the chamber. The input electrodes are configured to cause the input direct current to induce motion in the plasma. Motion induced in the plasma transforms current flowing there-through. At output electrodes extend from the chamber. The output electrodes conduct a second direct current, from the induced motion in the plasma, for delivery from the chamber.

摘要： In this container refrigerator, the permissible equivalent negative-phase-sequence current of a generator to be connected is calculated in Step S3 based on its capacitance. Next, in Step S4, the power consumption of an inverter device to generate the equivalent negative-phase-sequence current is calculated. Then, in Step S6, the equivalent negative-phase-sequence current generated by the container refrigerator is calculated based on the power consumption of this inverter device. Thereafter, in Step S9, It is compared to Itg. If It>Itg is satisfied, It is restricted until It≦Itg is met by lowering the output frequency of the inverter device repeatedly in multiple stages. Consequently, even if the generator connected has small capacitance, the operation may be continued at a number of rotations appropriate for that small capacitance without causing the generator to overheat or be burned out.

摘要： A power source device includes: a transformer; a switching section driving a primary side of the transformer; and a controller capable of performing a switching operation on driving of the switching section for controlling an output of a secondary side of the transformer. The device detects a drive frequency for the switching section in the switching operation, and switches the drive frequency so as not to be a frequency in a prescribed range when the detected drive frequency reaches a threshold.

摘要： The disclosure provides a non-contact power receiving apparatus including a conductive pattern in a second region of a substrate not covered by a magnetic sheet. The conductive pattern includes first and second electrodes provided in a first plane parallel to a surface of the substrate and arranged in a length direction of the conductive pattern. A third electrode is formed on a second plane parallel with the first plane. A first via hole connects superposed portions of the first and third electrodes to each other, and a second via hole connects superposed portions of the second and third electrodes to each other. As a result, loops of eddy currents generated in the conductive pattern can be made to be small, whereby eddy current loss can be reduced.

摘要： The interface has three inputs, a first output which is connected to a first input, a second output which can be connected to a second input or to the third input. The interface also includes a switching device which is connected to the second input, the third input and the second output, and a control device which is coupled to the third input in such a way that a detection signal can be fed from the third input to the control device. The detection signal is indicative of whether the second input or the third input is connected to the second pole of the two-pole line.

摘要： A system and a method of long-term condition monitoring of structures are based on use of autonomous sensing modules, centers for storing and processing data and software for data analysis. An autonomous sensing module contains a set of sensors for measurements of parameters related to the condition of a monitored structure, a non-volatile memory, a wireless data transfer unit, a controller, a clock circuit, a battery, an energy harvesting device and a power management unit. The autonomous sensing module provides a very long-term (40 years or more) functionality and reliability due to both use of at least near hermetic packages for the controller, the non-volatile memory, the battery, the clock circuit and the power management unit and choosing the duration of periods when the sensing module works in active mode in such a way that the average energy consumed by the autonomous sensing module is fully compensated by the average energy harvested by the energy harvesting device.
