摘要： Aircraft power distribution systems and methods for regulating a system voltage in aircraft power distribution systems are described. An example system includes a first generator, a first power feeder, a second power feeder, a first load, a second load, and a plurality of contactors. The first power feeder and the second power feeder are coupled in parallel between the first generator and a power panel. The first load is coupled to the first power feeder, and the second load is coupled to the second power feeder. The plurality of contactors is configurable to transfer power in a first direction from the first generator to both the first load and the second load during a first mode of operation, and configurable to transfer power in a second direction from the power panel to the first load or the second load during a second mode of operation.

摘要： An assembly for connection to a high-voltage system has multiple single-phase transformers each having a transformer tank which is filled with a fluid and in which a core with at least one winding is situated. At least some of the windings of the single-phase transformers are connected to one another, forming a neutral point. A short-circuit voltage curve or impedance of the assembly can be adapted to different requirements. The windings are each connected to the neutral point via a switchover unit and a choke winding. The choke winding has multiple tappings, and the switchover unit is configured to select the tapping via which the winding in question is connected to the neutral point.

摘要： A two-wire load control device may be configured to compute an accurate estimate of real-time power consumption by a load that is electrically connected to, and controlled by, the two-wire load control device. The load control device may be adapted to measure a voltage drop across the device during a first portion of a half-cycle of an AC waveform provided to the device. The device may be further configured to estimate a voltage drop across the load during the second portion of the half-cycle. The estimated voltage drop may be based on the measured voltage drop. The device may be further configured to measure a current supplied to the load during a second portion of the half-cycle. The device may be configured to estimate power consumed by the load based on the measured current and the estimated voltage drop.

摘要： Disclosed herein are system, apparatus, article of manufacture, method, and computer program product embodiments for modifying the functionality of an alternating current (AC) controlling device. An example computer-implemented method includes determining whether an electrical terminal of an AC controlling device is connected to a grounded conductor. In response to determining that the electrical terminal is connected to the grounded conductor, the example computer-implemented method includes generating a first control signal configured to permit the AC controlling device to perform a function. In response to determining that the electrical terminal is not connected to the grounded conductor, the example computer-implemented method includes generating a second control signal configured to prevent the AC controlling device from performing the function.

摘要： An irrigation system comprises an irrigation controller that receives user input and provides a power signal and command and message data to an encoder. The encoder encodes the command and message data onto the power signal to provide a data encoded power waveform that is sent over a two-wire path. The irrigation system further comprises one or more decoders in communication with the two-wire path to receive the data encoded power waveform and one or more irrigation valves in communication with the one or more decoders. The data encoded power waveform provides power to the decoders and the decoders decode the command and message data from the data encoded power waveform to control the irrigation valves according to the user input.

摘要： Examples described herein provide an apparatus having a circuit with a grounding circuit and a switch. The apparatus generally includes a gate induced drain leakage (GIDL) protection circuit coupled to the switch and to an output voltage. The GIDL protection circuit may include a switch protection circuit configured to maintain a drain voltage of the switch less than a first supply voltage (Vdd) when the circuit is in an OFF state; and a ground protection circuit configured to maintain a drain voltage of the grounding circuit less than the first supply voltage when the circuit is in an ON state.

摘要： An electrosurgical generator supplies, during operation, a high-frequency alternating current to an electrosurgical instrument for plasma cutting of body tissue. The electrosurgical generator has outputs for connecting an electrosurgical instrument to supply an electrosurgical instrument connected to the outputs with a high-frequency alternating current, and for determining the impedance of a load connected to the outputs. The electrosurgical generator features impedance and voltage measuring units as well as an output voltage control unit. The output voltage control unit is designed to control the AC output voltage depending on a maximum output voltage value that is set during operation depending on an output value of the impedance measuring unit and/or depending on an output value of the voltage measuring unit, such that the maximum output voltage value predefines a lower AC output voltage during a vaporization phase than during an ignition phase occurring subsequently to the vaporization phase.
