Abstract

Abstract:The switch boostinverter is a single stage power converter which is derived from the inverseWatkins Johnson topology .Here these type of switch boost inverter can able toproduce  an output voltage that isgreater than or less than available dc input voltage This is not happened involtage source inverter. Also it has a property i.e. better electromagneticinterference noise immune if we compared with voltage source inverter. It alsohave a property like a compact design of power converter .We have greatadvantage of sbi is that it can supply both ac and dc power simultaneously froma single unit of dc supply. Because of this it is suitable for dc Nano gridapplication .In our research paper ,the sbi is use like a power electronicinterface in a direct current supply .Now we are going to discussed about theswitch boost inverter based Nano grid in detail .In this paper we will alsopresent the dq synchronous references -frame-based it is nothing but thecontroller used for sbi ,which are regulate the ac and dc bus voltage understeady state as well as dynamic load variation occur in the Nano grid at thegiven reference
