摘要： 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.

摘要： A wind turbine generator 1 is connected to a section 2 of an electricity grid 3 via a converter 4, which converts the ac output power from the generator into three-phase electric power at the voltage and frequency of the grid 3. The converter 4 comprises silicon carbide transistors which act as ON-OFF switches which are controlled so as to create a voltage profile which is the same as that of the grid voltage. Each grid section 2, 2′ has a respective circuit breaker 10, 10′ which disconnects the associated section from the remainder of the grid 3 in the event of an abnormally high current. The converter 2 includes a fault detector 11 arranged to detect grid faults, such as an abnormally low voltage level which, in response, generates an alarm signal which causes a high-level transient current to be supplied to the grid 3 sufficient to trip the circuit breaker 10′ so as to disconnect the faulty section of the grid. By using silicon carbide transistors, which can withstand high operating temperatures, a higher-level current can be generated than would be the case with converters using conventional silicon transistors.

摘要： A controller for a brushless motor that is configured to operate in normal mode or under-voltage mode. When operating in normal mode, the controller generates control signals for exciting a winding of the motor, monitors the magnitude of an input voltage, and switches to under-voltage mode in the event that the input voltage drops below an under-voltage threshold. When operating in under-voltage mode, the controller suspends excitation of the winding, monitors the magnitude of the input voltage, monitors the magnitude of a supply voltage used to power the controller, switches to normal mode in the event that the input voltage exceeds a restart threshold, and resets itself in the event that the supply voltage drops below a brown-out threshold.

摘要： Methods and circuits for undiscoverable physical chip identification are disclosed. Embodiments of the present invention provide an intrinsic bit element that comprises two transistors. The two transistors form a pair in which one transistor has a wide variability in threshold voltage and the other transistor has a narrow variability in threshold voltage. The wide variability is achieved by making a transistor with a smaller width and length than the other transistor in the pair. The variation of the threshold voltage of the wide variability transistor means that in the case of copies of intrinsic bit elements being made, some of the “copied” wide variability transistors will have significantly different threshold voltages, causing some of the intrinsic bit elements of a copied chip to read differently than in the original chip from which they were copied.

摘要： This relates to detecting unwanted couplings between a protected terminal and an adjacent terminal of an IC controller of a power supply. The voltages across adjacent terminals are monitored. If the voltage difference between the terminals falls below a minimum threshold for greater than a first duration of time, an internal current source injects current into one of the terminals. If, within a second duration of time, the injected current pulls the voltage of the injected terminal to a voltage that causes the voltage difference between the terminals to be above the minimum threshold, it may be determined that a transient fault has occurred and been cleared or falsely detected. If, however, the injected current does not pull the voltage of the injected terminal to a voltage that causes the voltage between the adjacent terminals to be above the minimum threshold, the fault condition is confirmed and switching is disabled.
