摘要
Circuits and methods for driving a load are disclosed. An exemplary driving circuit may include a plurality of switching devices and a controller electrically connected to the plurality of switching devices. The controller may be configured to provide a switching signal for controlling switching operations of the switching devices. The controller may also be configured to determine whether the switching signal falls within a predetermined dead zone. When it is determined that the switching signal falls within the predetermined dead zone, the controller may be configured to modify the switching signal by moving a space vector corresponding to the switching signal to a boundary of the predetermined dead zone. In addition, the controller may be configured to provide the modified switching signal to the switching devices.
