Single phase seven level Z-source cascaded H-bridge inverter for photovoltaic systems

<p>The Multilevel inverter (MLI) is identified as a viable power electronic unit for distributed energy conversion applications. In this paper discusses the performance of single phase seven level Z (impedance) source cascaded H-bridge topology suited solar photovoltaic systems. A modified sinusoidal pulse width modulation technique used to control switches inverter. The simulation results are obtained interms output voltage and harmonic analysis confirm improvement in boost reduction distortion suggested topology. experimental matches with values, verified through scaled down prototype.</p>
