車両用の制御機器の過電圧保護回路、車両用の制御機器および車両用の制御機器の過電圧保護回路のテスト方法

Japanese Patent JP7206384

B2

An overvoltage protection circuit for a control unit for a vehicle includes an input terminal for applying an electrical input voltage, a test terminal for applying an electrical test voltage, and an output terminal for providing an electrical output voltage to supply the control unit. The overvoltage protection circuit also includes a reference device to provide a reference voltage using the input voltage. The overvoltage protection circuit includes a dividing device to provide a divided voltage using the output voltage. The overvoltage protection circuit includes a control device to provide a regulation signal using the reference and divided voltages. The overvoltage protection circuit includes a regulation device connected between the input and output terminals. The regulation device provides the output voltage using the input voltage and the regulation signal. The overvoltage protection circuit includes a modification device to modify a value of the divided voltage using the test voltage.
