摘要
This paper presents a simplified SVPWM signal generation technique for a five phase induction motor fed by cascaded H-bridge five-level inverter. This technique directly calculates the switching time of inverter switches using only the sampled amplitude of reference phase voltages making the carrier based PWM technique easy to implement for higher levels of inverter. The proposed algorithm is derived for different modulation region (i.e. m < 0.433 and m < 0.866) and their respective variation in voltage waveform is observed. Also, the response of five level inverter fed five phase induction motor is observed in terms of electromagnetic torque, speed and stator current. The simulation analysis is carried out using MATLAB/Simulink.
