Abstract : A closed loop bidirectional ac to ac buck boost converter circuit using power MOSFET is analyzed for reducing the output voltage sag and improving efficiency of the converter. The regenerative dc snubbers are used directly to power semiconductor switches to absorb energy stored in stray line inductances. These dc snubbers enhance the conversion efficiency as it has very simple structure consisting only of a capacitor. A fast response peak voltage detector for fast output voltage control is also proposed. It is observed from the simulation results obtained using MATLAB simulink, that the proposed closed loop scheme gives good dynamic and steady state performances with a high-quality output voltage, improved power factor, low harmonics, improved efficiency and significant reduction of the filter size.
