MultilevelInverter Technology for Induction Motor Drive by Sinusoidal PWM Technique
Keywords:
Diode clamped, Multilevel Inverter, Induction motor, SPWM technique, THDAbstract
Multilevel inverter is more recent and popular type control of power electronic converter that synthesizes a
desired output voltage from several levels of dc voltages as inputs. The poor quality of voltage and current of a
conventional inverter fed induction machine is due to the presence of harmonics and hence there is significant level of
energy losses.In the proposed scheme a diode clamped three level inverter fed induction motor is simulated by SPWM
technique. This circuiteffectively control drive performance through reduction in total harmonic distortion (THD).
