  • Power control device for vehicle
    Patent number: 7259470
    Abstract: In a power control device for a vehicle, a monitoring control device 2 disposed separately from a power converter 1 judges normality/abnormality of the power converter 1, and sets an abnormality-occurrence electric generation switching signal 4 to ON/OFF, whereby a first electric generation control function corresponding to an output of power element driving signal generating means is forcedly stopped, and also a second electric generation control function based on a diode rectifying mode of a power element is started.
    Type: Grant
    Filed: October 14, 2004
    Date of Patent: August 21, 2007
    Assignee: Mitsubishi Denki Kabushiki Kaisha
    Inventor: Syougo Matsuoka
  • Single module electric power conversion apparatus
    Patent number: 6888729
    Abstract: To perform a miniaturization and weight reduction of an electric power conversion apparatus, and in extension, the miniaturization of an inverter apparatus itself. In the inverter apparatus which converts a DC voltage into an AC voltage, a semiconductor device for electric power conversion, and a drive and protection circuit which drives and protects this semiconductor device for electric power conversion, and a power supply circuit which supplies power to this drive and protection circuit are integrated in the same module.
