Abstract
An object of the present invention is to reduce an inductance of a power circuit, reduce a switching loss and a noise level and improve a voltage-use ratio of a battery power in a redundant-type electronic control device. An electronic control device that controls a motor has power modulesto drive the motor. Power terminalsandof the power moduleare arranged in positions that are close to and face power terminalsandof the power module, which are opposite to the power terminalsandof the power modulein polarity. Power terminalsanddrawn from a longitudinal end portionof the power moduleare arranged in positions that are close to and face power terminalsanddrawn from a longitudinal end portionof the power modulewhich are opposite to the power terminalsandof the power modulein polarity.
