Since a safety function is integrated into a power supply IC, reliability can be improved. An electronic control device for power conversion includes: a power module configured to convert DC power into AC power and supply the AC power to a motor; a gate driver configured to control the power module; a microcontroller configured to control the gate driver; a power supply IC configured to supply power to at least one of the gate driver and the microcontroller; a discharge circuit configured to discharge a high voltage supplied to the power module; and a sensor. The power supply IC includes a microcomputer abnormality detection circuit configured to detect an abnormality of the microcontroller and a safety processing circuit configured to determine necessity of safety processing based on an output of at least one of the microcomputer abnormality detection circuit and the sensor and performs the safety processing. The safety processing circuit stops the motor or discharges a high voltage using the discharge circuit.
