In this book an attempt has been to circuit modeling and simulation of dynamic voltage restorer (DVR) using cascaded five level inverter. However, under input disturbances noise is present in the response characteristics. Multilevel cascade inverter with separate dc sources has been proposed for sensitive load. Simulation results have shown that with control strategy that operate the switches at fundamental frequency. These inverters have low total harmonic distortion (THD) and high efficiency. The main advantages of using multilevel inverters for sensitive load is given as follows: It is...
