| 摘要 |
This control board for a power conversion device comprises a board body, a power-supply generation section that is provided on the board body and has a ground terminal, a temperature detection section that is provided on the board body and detects the temperature of a switching element in the power conversion device, a drive section that is provided on the board body and generates a drive signal that drives the aforementioned switching element, and a ground-potential section provided on the board body. The ground-potential section contains the following: a first conductor section that extends from the ground terminal of the power-supply generation section to an initial branching point; a second conductor section that branches at said initial branching point, extends to the abovementioned temperature detection section, and downstream of the initial branching point, electrically connects to the temperature detection section only; and a third conductor section that branches in a different direction from the second conductor section at the initial branching point and extends to the abovementioned drive section. |
