Abstract
The 3-level inverter is applied to the induction motor drive as the voltage type inverter for large poller one. This inverter divides the DC link voltage into the two parts and it is supplied to the inverter. The 3-level inverter can reduces the voltage between the each devices, and get more sinusoidal current waveform. This paper presents the new PWM method which can reduces the harmonics. The modulation at the inverter side is implemented using a DSP microprocessor.
