Com pa ed to the t ad itiona l t ansfo m, the new AC pow e sou ce can a- ch ieve sm alle size, h ighe efficien t and continuously va iable outpu t vo ltage in pow e conve sion, and the output of vo lt- age is not affected by load when the feedback cont o l loop is used in the AC sou ce. H av ing analyzed the p inc ip le of communication and cont o l st a tegy of the AC sou ce in de tai,l at the end of the pape we have p esented the esults of a compute smi u lation and m ode l test.
