摘要
A motor driver may include a controller, a space vector modulator, a converter and a detector. The space vector modulator may generate driving signals under control of the controller according to a space vector pulse width modulation (“SVPWM”) scheme. The converter may derive AC signals from the driving signals received from the space vector modulator and may output the AC signals to the USM motor. The detector may generate feedback signals representing current and voltage supplied to the USM motor. The controller may revise estimates of space vectors, based on measurements from the detector, to control the space vector modulator to adjust frequencies, amplitudes, or phase angles of the plurality of AC signals.
