Multilevel inverters are very popular and have many applications in electric utility and for industrial drivers. As the number of levels in multilevel inverter increases, THD decreases accordingly. The paper compares three different topologies of inverters (Diode clamped inverter, Flying capacitor inverter and Cascaded H-bridge inverter). The comparison is done with respect to cost, power losses and THD. MOSFETs and IGBTs are used a switching devices for analysis. Tradeoff between the power losses and cost is also discussed in this paper. To select a multilevel inverter is a tradeoff between cost, complexity, losses and THD. The most important part is to decide which one is more important.
