  • Patent number: 10374414
    Abstract: A semiconductor power module with which it is possible to suppress the influence of noise given from a main terminal to a control terminal is provided. At least any one of main terminals (positive electrode terminal, negative electrode terminal, alternating current terminal) is so configured that the main terminal includes two parts extended in a common direction. The two parts are, for example, formed of a single component having such as a shape that the component is bifurcated from the outside toward the inside of the semiconductor power module or two different components. The two parts are so structured that the parts are extended in a common direction. Control terminals (gate signal terminal and emitter signal terminal) are so arranged that a laminated portion of the control terminals is sandwiched between one and the other of the two parts to configure the semiconductor power module.

  • Patent number: 10044220
    Abstract: When the power is normally supplied from the commercial power supply, the storage battery is charged by reducing the DC voltage by the charge/discharge chopper. The switching unit is provided in the previous stage of the converter. When the commercial power supply is in an abnormal state, the three-phase AC converter is operated as three discharge choppers connected in parallel by supplying the power of the storage battery to the converter and boosting the power by the switching element included in the converter. The power of the storage battery is boosted by the charge/discharge chopper, and a part of the discharging power is supplied. One three-phase AC reactor is provided in the previous stage of the converter, and the three-phase AC reactor has three coils, magnetic leg iron cores having the coils winding around them, and one leg without a coil winding around it connected in parallel.
