A Power Decoupling Method Based on Four Switch Three-Port DC/DC/AC Converter in DC Microgrid

Power maintenance in a real time microgrid plays an important role in today's scenario. This paper describes a power decoupling approach using a four-switch three port DC/DC/AC converter in a DC microgrid. The system is designed with three topologies connected with a DC source, a capacitor and an AC port. The power flow control technique is used so that the converter is decoupled to obtain low frequency ripple power. The system is compact and cost effective. The system is designed with two inductors current control. Results show that the described topology is feasible and analyzed the designed power control technique.
