Study of Three Phase Cascaded H-Bridge Multilevel Inverter For Asymmetrical Configuration

We know that, the inverters are broadly classified as two level inverters and multilevel inverters. This conventional inverters have many limitations at high power and high voltage applications. However, the multilevel inverter becomes popular for high power and high voltage applications due to their increased number of levels at the output. As number of levels increases, the harmonics are redu...
