An attempt to Design and Analysis of Multilevel Converter Topology for Renewable Energy Applications

Multi-level inverter system architecture and simulation has great potential to integrate and expand the solar photovoltaic system. The multi-stage inverter design is based on a number of topologies. The improved space vector pulse width modulation makes it possible both in qualitative and quantitative terms to improve systems efficiency and production. The device can be connected to the photovoltaic solar system. Generated DC power is link to the AC grid through the inverter and power transformers. Harmonic filters and massive, expensive, and lossy transformers are used in traditional inverters. Multi-level inverters with lower Total Harmonic Distortion (THD), inductor-free design and increased control range are a viable alternative to conventional inverters. They create a steps-like waveform that looks a lot like a sine wave. Smart grids can include a lot of distributed sources, and if those sources have low THD, filtering them at the common point of connection isn't as difficult. This paper proposes 19-level inverter with high boosting power and minimal THD. Phase Opposition Disposition Pulse Width Modulation (PODPWM) technique modulates the inverter switches for voltage balance and switching losses minimization.
