AdviserProfessor Jin WangAbstractA power electronics devic SIMULATION AND IMPLEMENTATION OF TWO LEV e which converts DC power to AC power at required output voltage and frequency level is known as an inverter. Two categories into which inverters canSIMULATION AND IMPLEMENTATION OF TWO LEV
be broadly classified arc two level inverters and multilevel inverters. Some advantages that multilevel inverters have compared to two level invertersSIMULATION AND IMPLEMENTATION OF TWO-LEVEL AND THREE-LEVEL INVERTERS BY MATLAB AND RT-LABTHESISPresented ill Partial Fulfillment of the Requirements f SIMULATION AND IMPLEMENTATION OF TWO LEV purpose applications, such as an active power filter, a static VAR compensator and a machine drive for sinusoidal and trapezoidal current applications. Some drawbacks to the multilevel inverters are the need for isolated power supplies for each one of the stages, the fact that they are a lot harder SIMULATION AND IMPLEMENTATION OF TWO LEV to build, they are more expensive, and they are more difficult to control in software.I llis focus of this thesis is the simulation study of single phSIMULATION AND IMPLEMENTATION OF TWO LEV

Software packages MATLABS1SIMULATION AND IMPLEMENTATION OF TWO-LEVEL AND THREE-LEVEL INVERTERS BY MATLAB AND RT-LABTHESISPresented ill Partial Fulfillment of the Requirements f SIMULATION AND IMPLEMENTATION OF TWO LEV inverters are modeled with resistive load and inductive load and then waveforms are observed. Secondly, a two-level inverter (single phase and three phase two-level inverter) is modeled by different ways and suitable switching control strategics (PWM technique) to carry out harmonic elimination.

Finally, all inverters models are modeled and run in real time by using RT-LAB and the results SIMULATION AND IMPLEMENTATION OF TWO-LEVEL AND THREE-LEVEL INVERTERS BY MATLAB AND RT-LABTHESISPresented ill Partial Fulfillment of the Requirements f SIMULATION AND IMPLEMENTATION OF TWO LEV n and compared. It is formed that in both real time and oft' time the results were acceptable. Also, some derivations, such as thirteen segments of region 1 for each sector, nine segments of region 2 in each sector, seven segments of region 3 for each sector for three-level inverter, which have neve SIMULATION AND IMPLEMENTATION OF TWO LEV r beeti mentioned before, are derived and the switching sequence for each region in each sector is drawn.illDedicationI wish to dedicate this diesis tSIMULATION AND IMPLEMENTATION OF TWO LEV
