Summary:The increase in the usage of renewable energy and power electronic applications prompted the development of multilevel inverters. A new multilevel switched capacitor boost inverter is designed which gives the required number of output voltage levels with a dc source. The number of power electronic components used here are less comparatively. A single inductor multi-output DC-DC converter is coupled with an inverter through dc link capacitor to carry active power to the grid. Hence this boost inverter shows good reliability, less cost and low losses. The dc linked capacitor helps in voltage balancing. The total harmonic distortion is reduced. the cascaded H-bridge converter has gained significant interest due to a modular structure with easy construction and maintenance, isolated dc buses with no voltage unbalance problem and easy extension. The inverter switches are triggered using Phase Opposition Disposition (POD) Pulse Width Modulation technique. Simulation for five level and seven level boost inverter topologies is done using MATLAB software and hardware implementation of five level boost inverter is executed.
