Abstract
A control device for a rotating electrical machine system having a plurality of rotating electrical machines is provided with a single current control circuit and a controller. The controller sets an operating point of at least one rotating electrical machine of the plurality of rotating electrical machines, and sets the current for each rotating electrical machine so that one of the efficiency of the current control circuit and the overall efficiency with respect to all the rotating electrical machines. The controller controls the current control circuit so that the current control circuit supplies a composite current to all rotating electrical machines, the composite current combining the set current for each rotating electrical machine.
