This paper proposes a simple and reliable Solid state transformer circuit for interfacing the wind power to the load. Three stage SST based on single active bridge (SAB) converter is capable of providing the voltage regulation under varying input and load with the help of simple voltage control loop and tuned PI controller by high frequency converter phase shift control. Circuit contains limited number of controlled devices switches at zero voltage enables to operate at high frequencies and has easy control strategy. The performance of circuit is verified through simulation studies.
