Usually practice, three-stage AC power supplies aren't the best choice for utility applications. Indeed, three-stage to single-stage, three-stage to double-stage, and three-stage to multiphase transformers are in use all over the world, and they are virtually all manufactured using the same techniques. Despite their enormous size and weight, such transformers have additional deadly characteristics, like as the ability to propagate a deficient current. For a long time, an Electronic Power Transformer, also known as a Power Electronic Transformer or a Solid Transformer, has been suggested. To construct a progression of capacity SEPT extraordinary EPT, we use a module made up of a three-stage Pulse Width Modulation rectifier, a medium recurrence transformer, and yield single-stage inverters in this work. In this article, we also discussed the SEPTs' adjustment methods, as well as extending the PARK change to four stages and proposing the change coefficients of the four-stage AC framework to the dqg0 framework straight away. In this article, a few instances are investigated, and the replication results show that SEPT has all of the advantages of EPT, such as more consistent state, better waveforms, better force factor, and so on, when compared to ordinary transformers.
