This paper presents, ant colony optimization based hybrid algorithm for selective harmonic elimination in single phase seven level multilevel inverter with reduced switches. For high power and high voltage applications, multilevel structure with selective harmonic elimination (SHE) modulation scheme is used. The output voltage of multilevel inverter contains fundamental component along with harmonics...
The grid connected inverters are increasingly used nowadays in distributed generation and smart grid. But the main challenge in grid connected systems is their compatibility with grid utility and also to maintain the harmonic contents of output current. To overcome these challenges, different current control techniques are used so far. This paper presents a multilevel inverter for single phase grid...
For medium and high voltage applications, Multilevel inverters have been widely used as a important devices. The advantages of multilevel inverters include low electromagnetic interference (EMI) outputs, low power dissipation, low harmonic etc. The most common multilevel inverter topology is cascaded H-bridge topology constituted by IGBT semiconductors. The most common switching technology used is...
