  • Patent number: 7400116
    Abstract: When a control means turns on a pre-charging contactor, an AC current from an AC power source is converted into a DC current by a switching circuit to charge a smoothing capacitor. However, the smoothing capacitor cannot be charged completely due to the operation of a capacitor of an LC filter. Therefore, when the voltage of the smoothing capacitor detected by a voltage detecting means exceeds a predetermined value, the smoothing capacitor is further charged by bringing the switching circuit into a boosting operation. Thus, even if an LC relay required in the prior art for invalidating the capacitor of the LC filter is not provided, it is possible to completely charge the smoothing capacitor, thereby providing a decrease in the number of parts and an enhancement in reliability of the pre-charging circuit, and preventing a reduction in performance of the LC filter due to a loss in the LC relay.

  • Patent number: 7388353
    Abstract: In discharging a smoothing capacitor connected to DC sides of first and second switching circuits, a DC-DC converter is first turned on to charge a battery for an auxiliary, thereby discharging the smoothing capacitor. Therefore, an electric charge of the smoothing capacitor can be effectively utilized to the maximum. When the voltage of the smoothing capacitor detected by a voltage detector is reduced to a predetermined value or less, and as a result the DC-DC converter is brought into an inoperable state, electric charge of the smoothing capacitor is consumed by at least one of a motor/generator and an LC filter connected to AC sides of the first and second switching circuits by driving at least one of the first and second switching circuits. Therefore, the smoothing capacitor can be completely discharged without need for a special discharging circuit.

  • Patent number: 7339411
    Abstract: A processor or a semiconductor integrated circuit has circuit blocks performing signal processing, internal power supply nets, noise detecting circuits corresponding to each circuit block that detect noise on the power supply nets and an interruption handling circuit that prevents a malfunction in processing within a circuit block caused by noise on the power supply nets. When noise is detected, the interruption handling circuit performs an interruption by sending an interruption signal to the circuit block relating to the signal processing for preventing a malfunction to the circuit block. During the operation of a plurality of stages for executing an instruction, noise is monitored at every stage. If no noise is detected through a final stage, the result is outputted. If noise is detected at any one of the stages, then an interruption process is performed.
