  • Electric compressor control device
    Patent number: 11888388
    Abstract: To provide a high-voltage apparatus control device capable of judging the connection state of a connector and discharging residual charge in a short time. A control device 1 controls an electric compressor and is provided with an interlock loop 4 annexed to a connector 9 for connecting the electric compressor to an HV battery 17. The control device 1 detects connection/disconnection of the connector 9 on the basis of the state of the interlock loop 4 and forcibly discharges residual charge in an internal smoothing capacitor 14 when disconnection of the connector 9 is detected.
    Type: Grant
    Filed: September 12, 2019
    Date of Patent: January 30, 2024
    Assignee: SANDEN CORPORATION
    Inventors: Yunhai Jin, Hiroshi Yoshida
