  • Publication number: 20240113648
    Abstract: A motor control apparatus includes: a converter circuit; an inverter circuit; a current detector; a regenerative resistor; a regenerative resistor controller; and a control device. The converter circuit converts alternating current from an alternating current power supply to direct current, converts regenerative direct current from the inverter circuit to regenerative alternating current, and further supplies the regenerative alternating current to the alternating power supply. The inverter circuit converts the direct current to alternating current for driving a motor, and converts regenerative alternating current from the motor to the regenerative direct current. The regenerative direct current from the inverter circuit passes through the resistor. The regenerative direct current passes thorough the resistor upon the current detector detecting the regenerative current exceeding a predetermined value.

  • Publication number: 20100127996
    Abstract: To provide an in-vehicle device including a layout-information acquiring unit, a relating unit, a combination display unit, a converting unit, and an output-signal transmitting unit. The layout-information acquiring unit acquires layout information of input keys of the portable terminal device. The relating unit relates each input key included in the layout information to a predetermined area on a touch panel display. The combination display unit causes a layout screen of each input key related to a predetermined area on the touch panel display to be displayed in the touch panel display. The converting unit converts an input to the touch panel display into an output signal corresponding to a pressing operation of the input key or a combination of the output signals, based on the layout information. The output-signal transmitting unit transmits the output signal obtained by conversion to the portable terminal device.
