Multilevel inverter plays an important role in the field of modern power electronics and is widely being used for many medium voltage and high power industrial and commercial applications. It has many advantages compared to conventional two level inverter such as high dc link voltages, reduced harmonic distortion, fewer voltage stresses, and low electromagnetic interferences (EMI). For higher voltage level it has some major disadvantages such as the use of higher number of voltage sources and power switches, voltage balancing issues and complex pulse width modulation control. In this paper seventeen level multilevel inverter with different Pulse width modulation(PWM) techniques are implemented and analysis of total harmonic distortion(THD) is carried out. proposed circuit topology which requires only nine switches and four dc sources. Design, simulation and comparison of different switching techniques like equal phase method, feed forward method, half equal angle method and half height method are carried out in MATLAB/Simulink environment.
