Title:
MOTOR CONTROL WITH VOLTAGE HARMONIC SHAPING
Document Type and Number:
WIPO Patent Application WO/2011/128695
Kind Code:
A3
Abstract:
A control system for an electric motor comprises a current sensing means arranged to produce a current sensing output indicative of electric current in the motor, current control means arranged to receive the current sensing output and to output a voltage demand indicative of voltages to be applied to the motor, and voltage demand correction means arranged to generate a correction signal and to use the correction signal and the voltage demand to produce a corrected voltage demand for voltage harmonic shaping.
