  "textContent": "A vehicle on-board power conversion device includes a power converter, a conversion device-side connector that is configured to be connected to an external connector, and a check circuit that is configured to check a connection state of the conversion device-side connector and the external connector. The power converter includes a microcontroller. The vehicle on-board power conversion device includes an isolator located between the check circuit and the microcontroller. The check circuit includes an inverting circuit that is configured to invert the signal including the square wave and generate an inverted wave. The microcontroller includes an output terminal configured to output a square wave, and a detection terminal configured to detect the square wave. The microcontroller determines whether there is an inter-terminal short-circuit anomaly based on a detection result of the detection terminal.",
