  • Patent number: 10434842
    Abstract: An in-vehicle inverter device includes a noise reduction circuit, which has a common mode choke coil configured to reduce common mode noise and normal mode noise contained in DC power, and an inverter circuit, which receives the DC power in which the noise has been reduced. The noise reduction circuit includes: an input-side capacitor and an input-side resistor provided on the input side of the choke coil; an output-side capacitor and an output-side resistor provided on the output side of the choke coil; a first filter circuit that includes the choke coil, the input-side capacitor, and the input-side resistor; and a second filter circuit that includes the choke coil, the output-side capacitor, and the output-side resistor. The first and the second filter circuits reduce leakage noise generated in the inverter circuit.

  • Patent number: 10020707
    Abstract: A motor-driven compressor includes a housing, a compression portion, and an electric motor, a drive circuit, a circuit housing, a control circuit, a communication lead, and a metal shielding member. The compression portion and the electric motor are received in the housing. The circuit housing is arranged outside the housing and defines an accommodation chamber that receives the drive circuit. The control circuit is configured to control the electric motor by controlling the drive circuit. The communication lead is connected to the control circuit and drawn from the inside to the outside of the accommodation chamber. The metal shielding member is arranged in the accommodation chamber and covers the communication lead. The circuit housing includes a metal shielding portion, which is electrically grounded. The shielding member is electrically connected to the shielding portion.

  • Patent number: 8272828
    Abstract: An object moving apparatus is provided which is different from coordinated conveyance through real-time information exchange between carriages only by wireless communication and which can move an object reliably and in a more stable manner by coordinated control of carriages without the object falling off. Arranged is a leader carriage A with a carriage body 2 travelable in all directions by travel drivers 1 and a lifter 5 attached to the carriage body via a link mechanism 3 for lifting up a vehicle 4 as object. The leader carriage is movable along a given target track. Further arranged is a follower carriage B with a carriage body 2 travelable in all directions and a lifter 5 attached to the carriage body via a link mechanism 3 for lifting up the vehicle 4. The follower carriage estimates and follows movement of the leader carriage so as to move the vehicle 4 in coordination with the leader carriage.
