To overcome the limitations of traditional multilevel inverter, in this book Z-source multilevel inverter is proposed. It comprised by Z-source network and multilevel inverter topology. Multilevel inverter has a unique structure they are specially suited for applications which need low THD. Multilevel inverter is a power electronic device built to synthesize a desired AC output voltage from several DC voltage sources. Multilevel inverter not only can generate the output voltage with very low distortion, but also can reduces the Electromagnetic Compatibility Problems (EMC). Proper selection of pulses in the Z-source MLI can limit the THD in the output voltage. Cascaded multilevel inverters have been developed for electric utility applications. This book provides features and control schemes of the cascaded multilevel inverter for utility applications including renewable energy, VAR compensation, voltage regulation and harmonic filtering in power systems.
