Abstract
A control board where the ground potential includes a first conductor extending from the ground terminal of the power source generator to a first branch, a second conductor branching at the first branch, extending to the temperature detector, and electrically connected to only the temperature detector on a downstream side of the first branch, and a third conductor branching in a direction not directed to the second conductor at the first branch and extending to the drive.
Claims3
A control board for a power conversion device, the control board comprising:
- a board body;
- a power source generator provided on the board body, the power source generator having a ground terminal;
- a temperature detector provided on the board body, the temperature detector detecting a temperature of a switching element of the power conversion device;
- a drive provided on the board body, the drive generating a driving signal driving the switching element;
- and
- a ground potential provided on the board body,
- wherein the ground potential includes a first conductor extending from the ground terminal of the power source generator to a first branch, a second conductor branching at the first branch, extending to the temperature detector, and electrically connected to only the temperature detector on a downstream side of the first branch, and a third conductor branching in a direction not directed to the second conductor at the first branch and extending to the drive.
