As a rule, three-stage AC power supply isn't generally the most ideal decision for utility applications. Indeed, there is a rating of three-stage to single-stage, three-stage to double stage and three-stage to multiphase transformers being in activity around the globe, which are practically all made by broad methods. Regardless of their colossal cubage and weight, those transformers have other lethal characters for example they can spread a deficiency current. EPT (Electronic Power Transformer, moreover called Power Electronic Transformer or Solid Transformer) has been proposed for quite a long time. In this paper, we utilize a module made out of the information three-stage PWM (Pulse Width Modulation) rectifier, medium recurrence transformer and yield single-stage inverters to structure a progression of capacity SEPT (exceptional EPT). We additionally talked about the adjustment techniques of the SEPTs in this paper,also, we extend the PARK change to four-stage and right off the bat proposed the change coefficients of four-stage AC framework to dqg0 framework. A few cases are being examined in this paper, and the aftereffects of the reproduction demonstrated that SEPT has all the focal points EPT has, for example, better consistent state, better waveforms, better force factor and so forth contrasted and general uncommon transformers.
