| 摘要 |
A control unit includes a power supply board on which a control power-supply circuit that generates a control voltage is mounted, a control board on which a control circuit that is operated based on the control voltage is mounted, and a connection medium that connects the power supply board and the control board to each other and is used to supply the control voltage from the control power-supply circuit to the control circuit. A signal ground of the control power-supply circuit and a signal ground of the control circuit are connected to each other via a frame ground without via the connection medium. |
