Voltage modulation for controlling a motor
Abstract:
A circuit for controlling a motor that includes control circuitry configured to generate, for a phase of the motor, a switching signal indicating to couple the phase to a first terminal of a supply for an entire portion of each switching cycle of a first plurality of switching cycles corresponding to a first range of electrical angles for the rotor and to couple the phase to a second terminal of the supply for a portion of each switching cycle of a second plurality of switching cycles corresponding to a second range of electrical angles for the rotor. The control circuitry is further configured to control the motor based on the switching signal.
