For high-power, high-voltage applications, multilevel inverters have gained widespread acceptance. Due to its rising advantages. In this paper a new circuit multilevel inverter, comparatively speaking to traditional inverters, this design requires less components as well as fewer gate drives and carrier signals. Because of this, both the total expense and complexity are drastically decreased, especially for higher output voltage levels. This circuit consists by two components one is level generation part contain by four switches and other one is polarity generation part comprise by H-bridge inverter that make up output voltage as a seven level. The portion that generates levels employs high frequency switches to produce various levels, and the part that generates the polarity of the output voltage is at line frequency. Additionally, it is more effective due to an inverter component that uses line frequency to operate switching power devices. As a result, there is no requirement for all switches to operate at high frequency, resulting in easier and more dependable management of the inverter. Here multicarrier Phase Disposition Sinusoidal Pulse Width Modulation (PDSPWM) technique regulates the operation of the inverter.It consists by three carrier signals instead of six carrier signal and it provide less THD of output voltage and current compare to other multicarrier sinusoidal pulse width modulation techniques. The design, analysis and control of the seven level inverter is demonstrated with the help of MATLAB/Simulink tool.
Key words: Multilevel inverters / Sinusoidal Pulse width Modulation / Total harmonic
