摘要： A rapid shutdown system includes a PV (photovoltaic) generator. It further includes a DC (Direct Current)-DC converter receiving power from the PV generator and outputting power. The DC-DC converter outputs power at a high voltage state or a low voltage state. It further includes a DC bus coupled to the DC-DC converter to receive the power outputted by the DC-DC converter. The DC bus is coupled to a system comprising a load. The DC-DC converter transitions from the high voltage state to the low voltage state based at least in part on an output current of the DC-DC converter transitioning below a threshold.

摘要： Methods and systems for arc detection are described. A controller can receive a bus voltage of a direct current (DC) bus connected to an energy source. The controller can determine whether the received bus voltage is less than a bus voltage threshold. The controller can, in response to determining the received bus voltage being less than the bus voltage threshold, determine an occurrence of an arc event in an apparatus that includes the DC bus and the energy source.

摘要： A power supply control device controls power supplied via a power supply switch. A backup circuit instructs an IPD to turn the power supply switch on or off, based on an instruction signal instructing to turn the power supply switch on or off. A MICOM transmits an ON signal instructing to turn on the power supply switch and an OFF signal instructing to turn off the power supply switch to the IPD via a communication line (Lc). The MICOM determines whether communication via the communication line (Lc) is interrupted. The MICOM, in the case of determining that communication is interrupted, causes the backup circuit to start instructing to turn the power supply switch on or off.

摘要： Apparatus and methods for amplifier input-overvoltage protection with low leakage current are provided herein. In certain embodiments, amplifier input circuitry for an amplifier includes a pair of input terminals, a pair of input transistors each having a control input (for instance, a transistor gate), a pair of protection transistors each connected between one of the input terminals and the control input of a corresponding one of the input transistors, and a bidirectional clamp connected between the control inputs of the input transistors. Implementing the amplifier input circuitry in this manner provides a number of advantages including, but not limited to, robust protection against input overvoltage and low input-leakage current.

摘要： An anti-fuse having two electrical connections is constructed by adding at least one zener diode and resistor to a power MOSFET. When the voltage across the two electrical connections exceeds the zener diode voltage and the maximum gate voltage of the MOSFET, the MOSFET burns out. This shorts out the device which can be used to bypass an LED or other load when that load burns out and forms an open circuit.

摘要： Fault detection during a power swing in a power transmission system is described. Voltage and current measurements are obtained for each phase at a terminal of the power transmission system. Based on measurements obtained, a value of change in an impedance angle for each phase-to-ground loop and each phase-to-phase loop for each sample of the voltage and current values is calculated, where the value of change in the impedance angle is a difference between impedance angles of two samples separated by a predetermined interval. The average values for change in impedance angle based on a predetermined number of values of change in the impedance angle for each phase-to-ground loop and each phase-to-phase loop is calculated. The average values are compared with a threshold range of change in impedance angle. Based on the comparison, a fault in one or more of the phase-to-ground loops or phase-to-phase loops is detected and classified.

摘要： This application relates to a charging protection circuit. The charging protection circuit implements overcurrent protection by using a four-terminal NMOS switching transistor. In the solution provided in this application, floating management is performed on a Sub port of the four-terminal NMOS switching transistor. Specifically, when the four-terminal NMOS switching transistor is turned on, potential of the Sub port is pulled up, to avoid an excessively large internal resistance of the four-terminal NMOS switching transistor caused by an excessively large voltage between the Sub port and a drain of the four-terminal NMOS switching transistor. In addition, this application further provides a charging circuit and an electronic device.
