Abstract

Official abstract text for this publication.

According to typical examples, the first stator winding having the lower rated voltage is connected to the second direct-current voltage source only when the rotation speed of the rotating electrical machine becomes high. Therefore, output in a high-rotation range can be ensured while preventing the second stator winding from reaching a heat-generation limit. Furthermore, such switching operations can be actualized by the first switch and the second switch. Therefore, a control device of a rotating electrical machine can be actualized by a relatively simple configuration.

First claim

Opening claim text (preview).

What is claimed is: 1. A control device of a rotating electrical machine, wherein the control device is provided with a first stator winding and a second stator winding that has a greater rated voltage than the first stator winding, the first stator winding and the second stator winding being insulated from each other, comprising: a first inverter that is connected to the first stator winding; a second inverter that is connected to the second stator winding; a controller that…
