PROBLEM TO BE SOLVED: To provide a control board for a power converter where a discharge circuit and a wiring pattern, through which a polyphase current for driving an auxiliary motor flows, are provided efficiently on a common board body.SOLUTION: A control board for a power converter in a vehicle system includes a board body of multilayer board, a discharge circuit mounted on the surface of the board body and operating, when collision of vehicle is detected, to discharge the charges stored in a smoothing capacitor, a circuit part mounted on the board body and forming a second inverter, and a wiring pattern formed on the inner layer of the board body, connected with the circuit part of the second inverter, and through which a polyphase current for driving the auxiliary motor flows. When viewing in a direction perpendicular to the surface of the board body, at least a partial mounting position of the discharge circuit is within a range circumscribing the wiring pattern.SELECTED DRAWING: Figure 3 |
