Switching controller for electric motors and related method of controlling electric motors
Abstract:
A switching controller of a poly-phase electric motor may generate, in a fully digital manner, a replica of the phase current and/or of the phase (star) voltage of one or more windings of the motor. The switching controller may use digital signals already available for driving the motor to reconstruct a replica of the phase current or the phase voltage, and thereby avoid the need for dedicated analog components for phase current or phase voltage determination.
