“…For low and moderate power applications, square and quasi-square waves are allowed but for high power application, we need sinusoidal waveforms with very low harmonic content. That's how, by using semiconductor based devices and different methods of switches pulse generation (SPWM [4], THIPWM [5] & PDPWM [6]) the value of harmonic content can be minimized. So, taking this in mind, our aim is to design such architecture of h-bridge inverter, so that we can reduce the harmonic content from it.…”

In present time, the application of the voltage source inverter (VSI) are rapidly been increasing. Different designing methods are followed for the construction of VSI. The purpose of adopting for different techniques of inverter design is to decrease the harmonic contents from the output waves of VSI. Hence the comparison of three different voltage source inverters with their different techniques is discussed in this paper for the purpose of reduction in harmonics. Total harmonic distortion (THD) analysis of all three VSI has been done. THD analysis of sine pulse width modulation (SPWM) and third harmonic injection pulse width modulation (THIPWM) is further discussed in two manners -over modulation and exact modulation. A unique type of 7 level 5 switch voltage source multi-level inverter with phase disposition pulse width modulation (PDPWM) technique is also discussed and its comparison is made with earlier two techniques. In renewable energy systems, we need to control the power generation in a very efficient manner. Hence these inverters with low THD values can be utilized in that field for reduction in losses and increase in efficiency of the renewable system. Simulation of all three techniques based VSI is done on MATLAB platform and THD is compared.

Inverters are basically power electronics devices that are used to convert DC power to AC at a required frequency and voltage level. Their main application area in real-time is in high voltage and high-power applications in which the switching stress as well as total harmonic distortion must be low. Multilevel inverter technology has been emerging in recent times, as a very important substitute in for high-power medium-voltage energy governed devices. Multi-level inverters also have a major role in interconnected grid systems used nowadays. There are several major topologies of multilevel inverters that exist in literature: Diode clamped (DMLI) (aka neutral-point clamped), and Flying capacitor multilevel inverter (FCMLI) (aka capacitor-clamped) [1] and Cascaded H-bridges converter (CMLI) (i.e., cascaded multicell using separate dc sources). This paper discusses the principal benefits and drawbacks of increasing the number of levels of the inverter and how it has an effect on the efficiency and losses in the MLI architecture and how this difficulty as well as the overall performance of the systems can be improved using a novel Bridged-Cascaded H-bridge MLI topology. There are n-level inverter topologies possible. The paper proposes a novel bridged-insert cascaded MLI topology. The focus of the paper is on 5-level inverter topologies. The simulation has been carried out using MATLAB/Simulink.
