Selective Harmonic Elimination for Solar Cell based Multi-Level Inverter System Using Moth Flame Optimization
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 12
Abstract
Themulti level inverter is powerful electronic device, which is widely used for high power utility application. The main purpose of the multi-level inverter is to provide sinusoidal wave from with low-level harmonic content to reduce distortion. For improvement of the quality of multilevel inverter output voltage it is required to reduce the harmonic level. The fully controlled bridge is used in multilevel inverter. The switching angles of the IGBT/MOSFET need to be controlled in specific pattern to eliminate the particular harmonic. The analytical calculation is possible to find the set of solution (switching angles) for harmonic elimination. As the levels of the inverter increases, the analytical method becomes complex and difficult. The use of the evolutionary algorithm becomes popular for identifying the optimum value of angles. In this paper, 5 level cascaded bridge inverter taken for selective harmonic elimination. For identifying the switching angle moth flame optimization technique is used.
