Conventional transformers made of copper and iron are one of the most costly and heavy device in electrical system. The conventional transformers are suffering from the drawbacks like they are heavy and bulky, sensitive to harmonics, voltage drop under load condition and concerns regarding mineral oil. To overcome these drawbacks new power electronic based transformers are developed. Many drawbacks of conventional transformer have been removed by Power Electronic Transformer (PET). Still PETs are suffering from drawbacks like less effective for power quality improvement, bidirectional power...
