PROBLEM TO BE SOLVED: To provide a parallel structure power device which allows for easy use of a power device in a spatially restricted environment, while reducing the size and cost of a motor drive, and allows for easy maintenance of motor drive state upon malfunction of a switch module.SOLUTION: A parallel structure power device includes an AC/DC conversion unit 20, a main drive unit 40, a sub-drive unit 45, a temperature sensor 50 for measuring and outputting the temperature of the main drive unit 40 and sub-drive unit 45, and a control unit 30 for rotating a motor 70 by individually controlling the main drive unit 40 or sub-drive unit 45 depending on the state of the motor 70, turning the currently driving main drive unit 40 or sub-drive unit 45 off when the temperature measured in a temperature sensor unit 50 goes above a predetermined temperature, and driving the main drive unit 40 or sub-drive unit 45 in stop state. |
