Three phase DC-link converters are popular choice in renewable energy systems and micro-grids. They employ hex bridge converters which allow bidirectional power flow. Due to intermittent nature of most renewable energy systems and varying loads in microgrids, it is important to have a reliable and robust control system. Various control methods for these systems based on 0dq approach and vector control are being implemented. Despite the energy loss in switches, these systems have been proven better than the conventional ones. This project aims to focus on the basics of ac-dc-ac conversion using a balanced three phase system. A control strategy is devised for the on demand active and reactive power flow in both directions. The system is simulated in MATLAB/Simulink and results are verified.
