This paper present control of parallel connected single-phase Bidirectional AC-DC converter for Microgrid
application. Depleting layer of fossil fuel with increasing demand of electricity renewable energy sources plays vital role
in existing environment. Smart grid is a newly immersing technology which drawback of existing power grid with
additional future. Microgrid is a part of smart grid used to supply small community such as residential areas, universities
etc. Bidirectional AC-DC converter plays important role for connecting renewable energy sources to microgrid. This
paper deals with the parallel connected single-phase Bidirectional PWM AC-DC converter which operates in rectification
and inversion mode. Double loop PI control is used to control the converter in either mode of operation. The parallel
connected single-phase Bidirectional AC-DC converter is simulated using MATLAB/Simulink.
