摘要： A control device includes a shot-pulse control unit that provides, at a time of starting a synchronous motor, a predetermined current to each phase of a stator of the motor for a short time; a detecting unit that detects a current flowing through each phase when the predetermined current is provided; an estimating unit that estimates a position of the rotor by comparing detected values; a voltage control unit that controls application of a voltage to the synchronous motor based on a high-pressure side pressure of the compressor when the compressor is failed to be started due to any cause; and a magnetism-resistant section having a conductive layer sandwiched by insulating layers. The magnetism-resistant section covers a portion of a substrate of the control device, and a portion at which the conductive layer is exposed is in contact with the housing or a part conducting heat to the housing.

摘要： There is provided an integrated electric compressor that can be made small in size while reducing radio noise effectively. In an inverter of the electric compressor, a snubber circuit 21 comprising a resistor R and a capacitor C is provided between input/output terminals 20 of a power source and a switching element 18. The snubber circuit 21 is formed by surface mounting a resistive element constituting the resistor R and a capacitor element constituting the capacitor C on a power board 16. A leakage current from a motor 19 is thus restrained and radio noise is reduced. The resistive element and the capacitor element constituting the snubber circuit 21 are preferably surface mounted on the power board 16 on the side opposite to the side on which a control circuit board is arranged.

摘要： The present invention has an object to provide an inverter system for a vehicle-mounted air conditioner that prevents noise from entering a control circuit and allows high speed communication. A motor control microcomputer 24 is isolated from a gate circuit 22, and communication therebetween is performed via a photocoupler 80. This suppresses the influence of noise resulting from changes caused by changes in voltage and current that occur in a high voltage system for driving a motor 30. Also, the motor control microcomputer 24 and a communication driver 27 can be directly bus-connected without a photocoupler, thereby allowing high speed communication therebetween.
