    摘要: In one example, an arc fault circuit interrupter (AFCI) is provided. The AFCI may include a plurality of current arc signature detection blocks configured to output a plurality of corresponding current arc signatures, and a processor. The processor may be configured to receive each of the plurality of current arc signature from each of plurality of current arc signature detection blocks, respectively, and generate a first trigger signal. The processor may be further configured to assess each of the current arc signatures, determine whether an arc fault exists based on the assessment, and generate the first trigger signal if an arc fault is determined to exist. A method for detecting an arc fault is also provided.

    摘要: In one example, a hybrid circuit interrupter may include a three-coil architecture, first coil circuitry, leakage detection circuitry, and a main processing circuit including a processor. The three-coil architecture may include a coil housing, three coils, and a plurality of coil assembly conductors. The coils may be disposed within the coil housing. The coils may be parallel and aligned. The coil assembly conductors may be at least partially disposed within the coil housing. The first coil circuitry may be connected to the first coil and may generate first coil signals. The leakage detection circuitry may be connected to the other coils and may generate a leakage signal. The processor may receive the first coil and leakage signals, determine whether an arc fault exists from the first coil signals, determine whether a ground fault exists from the leakage signal, and generate a first trigger signal if a fault is determined.

    摘要: A semiconductor device includes a semiconductor substrate in which an active region and an edge termination region are defined, a semiconductor element formed in the active region, and first to fourth P layers formed in a region spanning from an edge portion of the active region to the edge termination region in the surface of the semiconductor substrate. The first to fourth P layers respectively have surface concentrations P(1) to P(4) that decrease in this order, bottom-end distances D(1) to D(4) that increase in this order, and distances B(1) to B(4) to the edge of the semiconductor substrate that increase in this order. The surface concentration P(4) is 10 to 1000 times the impurity concentration of the semiconductor substrate, and the bottom-end distance D(4) is in the range of 15 to 30 μm.
