Objectives This paper proposes a control methodology of bidirectional Converter for grid connected systems. Methods/ Statistical Analysis: The bidirectional converter is used for converting the DC-AC power by using decoupled current control strategy in stationary reference frame. The simulations of the proposed system are carried out in PSIM software. An experimental prototype of Bidirectional converter has been built in the laboratory. A TMS320F28335 digital signal processor (DSP) is used for generating the control pulses for the Converter. Findings: The control of grid converter along with battery backup would provide support to the grid. Thus the proposed control strategy could independently control active and reactive power and also able to avoid grid failures. Application/Improvements: Reduction of operating switching frequency, improved dynamics as well as robustness against grid impedance variation are some of the improvements of proposed system.
