Five Level Cascaded MLI

single phase 5- level Cascaded H Bridge Inverter by using MATLAB software

The cascaded H-bride multilevel inverter is to use capacitors and switches and requires less number of components in each level. This topology consists of a series of power conversion cells and power can be easily scaled.The combination of capacitors and switches pair is called an H-bridge and gives the separate input DC voltage for each H-bridge. It consists of H-bridge cells and each cell can provide the three different voltages like zero, positive DC, and negative DC voltages.One of the advantages of this type of multi-level inverter is that it needs less number of components compared with diode clamped and flying capacitor inverters. The price and weight of the inverter are less than those of the two inverters. Soft-switching is possible by some of the new switching methods.
