| description | Circuits, methods, and systems for driving a load are described. An exemplary driving circuit may include a plurality of switching devices and a controller electrically connected to the switching devices. The controller may be configured to receive a reference voltage signal indicating a target voltage for the driving circuit to generate to drive the load. The reference voltage signal may correspond to a reference space vector in a reference frame. The controller may also be configured to determine that the reference space vector falls within a holding region in which the reference voltage signal is subject to over-modulation. The controller may then generate an adjusted reference voltage signal by adjusting the reference space vector to match a predetermined space vector associated with the holding region. In addition, the controller may be configured to provide the adjusted reference voltage signal to the plurality of switching devices to drive the load. |
