Abstract: Connecting the power semiconductor devices in series can achieve higher voltage rating of inverter. Multilevel is one of these series connections of power semiconductor devices. Multi-level DC/AC Inverters have low voltage jump and smooth waveform in comparison to the PWM inverters. Most importantly, Multi-level DC/AC Inverters can achieve lower THD value. On the other hand, Diode-clamped DC/AC Inverters have simple structure and easy operation.For multilevel inverter, higher quality output voltage can be achieved by increasing the number of level and selecting the appropriate switching angles. The multilevel inverters operate at fundamental frequency, so that the switching loss can be reduced comparing to PWM inverter.The main objective of this project is to find out the best switching angles for different level of diode clamped inverter and simulate a few level of diode clamped inverter.
