Using space vector pulse-width modulation (SVPWM) signal transformation method, speed regulation of induction motor is implemented by controlling the duty ratio of every converter switch.
The working principle and performance characteristic of asynchronous motor cascade velocity modulation are analyzed, and the inner feedback cascade velocity modulation is introduced systematically.
