Disclosed is a power conversion apparatus that improves the reliability of a redundant system therefor. The power conversion apparatus includes a motor having a cylindrical motor case, a multi-phase stator, and a rotor, a power conversion section that switches the supply of electrical power to the motor, a control circuit board that controls the power conversion section, and a cover made of metal on which the power conversion section and the control circuit board are mounted. The power conversion section includes a first power conversion section and a second power conversion section. The cover includes a protrusion that protrudes toward the motor from a surface substantially parallel to the radial direction of the motor. The protrusion is formed in such a manner as to separate the first and second power conversion sections from each other.
