摘要： An over-voltage protection circuit includes an over-voltage detection circuit, a voltage generator and a switch for providing over-voltage protection between two pins of a USB Type-C port. The over-voltage detection circuit provides an over-voltage signal according to the level of the second pin. The switch includes a first end coupled to the first pin, a second end coupled to the second pin and a control end coupled to a control signal. When the over-voltage signal does not indicate an over-voltage occurrence at the second pin, the voltage generator provides the control signal having a first level for operating the switch in a first region. When the over-voltage signal indicates an over-voltage occurrence at the second pin, the voltage generator adjusts the control signal to a second level for cutting off the switch. The switch operates in a second region after the over-voltage occurrence and before the switch is cut off.

摘要： A current control device brings, after a target current has been changed to an upper side, a solenoid into a full-on state at a first timing that arrives in a predetermined control transition cycle shorter than an on-off cycle, determines whether an excitation current has become equal to or larger than a full-on threshold larger than the target current, brings the solenoid into a full-off state at a first timing that arrives in a predetermined energization switching cycle shorter than the on-off cycle after the excitation current has become equal to or larger than the full-on threshold, determines whether the excitation current has become equal to or smaller than a full-off threshold smaller than the target current, and causes a transition to a steady control at a first timing that arrives in the control transition cycle after the excitation current has become equal to or smaller than the full-off threshold.

摘要： A leakage current protection device with automatic reset after power outage includes a switch, a power supply module, a leakage current detection module, a self-testing module, a drive control module, and a first reset module. The drive control module drives the switch based on a leakage current signal from the leakage current detection module and/or a self-test fault signal from the self-testing module. The first reset module functions to automatically set the leakage current protection device in a connected state when power resumes after an outage. Another leakage current protection device with manual reset after power outage includes similar components above and also a second reset module, which functions to automatically set the leakage current protection device in a disconnected state when power resumes after an outage; the device can then be manually reset using a reset switch. These two devices can suit different needs of different electrical appliances.

摘要： The invention provides a method and device for fault section identification in a multi-terminal mixed line. The method comprises obtaining positive sequence voltage and current phasors from measurements of voltages and currents at each terminal of the mixed line. The method further comprises calculating a voltage phasor for each terminal, wherein the calculation of the voltage phasor for a first terminal is performed using at least the voltage and current phasors obtained for one of a second terminal and a third terminal, and the current phasor obtained for the first terminal. Thereafter, the method comprises determining a section of the mixed line having the fault, based on comparison of the calculated and obtained voltage phasors for each terminal. In addition, the method comprises controlling a switching device with a re-trip signal generated based on the determination of the section with the fault.

摘要： Systems and methods of detecting failures in an assembly that uses a variable differential transformer sensor. In one embodiment, a signal processor receives an excitation signal applied to the sensor, and detects a zero-crossing of the excitation signal. The signal processor receives an output signal of the variable differential transformer sensor in response to the excitation signal, and detects a zero-crossing of the output signal. The signal processor detects a fault in the assembly responsive to a determination that the zero-crossing of the output signal is separated from the zero-crossing of the excitation signal by more than the detection threshold.
