A control unit calculates the temperature difference between the ambient temperature of the electrical wire and the electrical wire temperature in time series, based on a previous temperature difference between the ambient temperature of the electrical wire 5 and the electrical wire temperature that was calculated previously, and the value of current flowing through the electrical wire. The control unit is configured to suspend this time-series calculation of the temperature difference, and clocks the elapsed time from suspension to resumption of calculation of the temperature difference. The control unit, in the case where calculation of the temperature difference is resumed, sets an initial temperature difference to be used as the previous temperature difference, based on the clocked elapsed time, in an initial calculation of the temperature difference after resumption.

  • Patent number: 10020116
    Abstract: Improved termination features for multilayer electronic components are disclosed. Monolithic components are provided with plated terminations whereby the need for typical thick-film termination stripes is eliminated or greatly simplified. Such termination technology eliminates many typical termination problems and enables a higher number of terminations with finer pitch, which may be especially beneficial on smaller electronic components. The subject plated terminations are guided and anchored by exposed internal electrode tabs and additional anchor tab portions which may optionally extend to the cover layers of a multilayer component. Such anchor tabs may be positioned internally or externally relative to a chip structure to nucleate additional metallized plating material. External anchor tabs positioned on top and bottom sides of a monolithic structure can facilitate the formation of wrap-around plated terminations.

  • Patent number: 9985429
    Abstract: Systems and methods for reducing inrush current into a component, such as a power converter (e.g., LED driver), which receives alternating current (AC) power from an AC power source (e.g., AC mains). The method may include pre-charging the input capacitance of a component or circuit for a determined period of time after closing of a control switch (e.g., photocontrol, contactor) using a capacitive load pre-charge circuit (e.g., resistor), and then shorting the capacitive load pre-charge circuit using a bidirectional AC switch coupled in parallel with the capacitive load pre-charge circuit after the determined period of time to selectively bypass the capacitive load pre-charge circuit. The bidirectional AC switch may include two source-connected metal oxide semiconductor field-effect transistors (MOSFETs) which have a very low “on resistance,” such that during steady-state operation, the protection circuit wastes very little power compared to conventional inrush protection circuits.

    Abstract: A protection device comprises a first substrate, a second substrate, a fusible element and a heating element. The first substrate comprises a first surface, and the second substrate comprises a second surface facing the first surface. The fusible element is disposed on the first surface of the first substrate, and the heating element is disposed on the second surface of the second substrate and is disposed above the fusible element. When over-voltage or over-temperature occurs, the heating element heats up to blow the fusible element and thereby providing over-voltage and over-temperature protection.

  • Patent number: 9972520
    Abstract: Disclosed is an aluminum nitride electrostatic chuck, comprising: a positioning electrostatic chuck and a carrier structure. The positioning electrostatic chuck includes a groove structure layer, a dielectric insulation layer, and a heat conduction layer. In the groove structure layer on the surface of the electrostatic chuck is provided with cooling gas channels, to facilitate control of the temperature distribution of a wafer. The electrostatic chuck is especially designed for use in a semiconductor manufacturing process of high temperature and high plasma power density. The dielectric insulation layer is provided with embedded electrodes, such that voltage conversion can be carried out to effect wafer absorption/release. The cooling gas channels are used to control temperature of the absorbed wafer, by means of heat conduction of aluminum nitride electrostatic chuck. Therefore, wafer temperature distribution is controlled through aspect ratio and geometry of cooling gas channel.

  • Patent number: 9967104
    Abstract: Circuits and techniques are described for detecting a ground fault leak between the PSE and the PD. Prior to PoDL voltage being applied to the PD, a test switch is temporarily closed for sensing a voltage drop in a loop between the positive terminal of the PSE voltage source and any ground leakage path between the PSE and the PD. If the resistance of the ground leakage path is below a certain threshold, a fault is declared. A similar test may be performed without a test switch by supplying a known test current through the loop and sensing the voltage drop. Another test is to connect the positive terminal of the PSE voltage source to the loop and sense the resulting current. After the full PoDL voltage is applied to the PD, a ground fault may be detected by sensing the equivalence between the source and return PSE currents.

  • Patent number: 9948085
    Abstract: An electric-wire protection device protects at least one electric wire among an electric-wire bundle that bundles a plurality of electric wires that are used to supply power to a plurality of loads from a power source Ba. Calculation circuit calculates an increased temperature of the electric wire from an initial temperature at the time that the estimate begins, based on a load current Is that has been detected and a thermal characteristic of the electric wire, and estimates the temperature of the electric wire by adding the increased temperature to the initial temperature. Current flow information supply portion supplies to the calculation circuit current flow information related to current flow to a load other than a subject load. Calculation circuit corrects the initial temperature by a correction value that corresponds to the current flow information that exists at the time the estimate begins.
