This inverter uses several H-bridge inverters connected in series to provide a sinusoidal output voltage. Each cell contains one H-bridge and the output voltage generated by this multilevel inverter is actually the sum of all the voltages generated by each cell i.e. if there are k cells in a H-bridge multilevel inverter then number of output voltage levels will be 2k+1. This type of inverter has advantage over the other two as it requires less number of components as compared to the other two types of inverters and so its overall weight and price is also less a k level cascaded H-bridge inverter.
