Multilevel voltage source inverter has been recognized as an important alternative to the normal two level voltage source inverter, especially in high power application. Using multilevel technique, the output voltage amplitude is increased, switching devices stress is reduced and the overall harmonics profile is improved. Three presentable topologies can b considered for multilevel inverter (ML...

Active power filter are been widely used for harmonic elimination. Harmonics are generated by nonlinear load in ac distribution system. The active power filters are broadly classified as shunt active power filter, series active power filter and hybrid filters. With regard to circuit topology, there are two basic kinds of active filter, voltage source and current source. The series active power ...

This paper presents a method to control both the dc boost and ac output voltages of Z-source inverter using neural network controllers. The capacitor voltage of the Z-source network has been controlled linearly in order to improve the transient response of the dc boost voltage of the Z-source inverter. The peak value of the line to line ac output voltage is used to control and keep the ac outpu...
