| 20110266984 | POWER DRIVE CONTROL DEVICE AND POWER DEVICE - A power drive control device is provided, in which, even if drive of a synchronous motor becomes impossible due to abnormalities of a control circuit for controlling the synchronous motor, it is possible to perform the drive control of the synchronous motor concerned easily with a simple configuration as emergency action. Failure of one of a first controller and a second controller is recovered by configuration of the other. Here, the first controller performs rotational drive control and regenerative control of a synchronous motor, based on a current signal of a fixed winding of the synchronous motor and a sense output from a rotation angle sensor of the synchronous motor, and the second controller performs power generation control of a synchronous generator based on a current signal of a fixed winding of the synchronous generator and a sense output from a rotation angle sensor of the synchronous generator. The drive control and the regenerative control (power generation control) which are performed by the first controller for controlling the synchronous motor and the second controller for controlling the synchronous generator are inextricably linked control. | 11-03-2011 |
