A New Topology DC-DC Bidirectional Converter for Hybrid Energy Integration System

Abstract

The preponderance of four-port converters at present accomplish power flow through the battery port, which is positioned on the low-voltage side. In other words, the battery receives energy from input sources and disbands it to the load. The system is helpless to manage it at a power level when there is this sort of power flow. An innovative multiport bidirectional DC-DC converter is proposed. When compared to the current converters, this conception requires the fewest devices due to the usage of a single-tapped power conversion mechanism rather than the center-tapped conversion already in use. The converter is indeed a wiser choice for DC micro grid applications due to its dual-directional power flow. First, the converter’s operating mechanism is assessed, subsequently; the converter is developed to fulfill the specifications for gentle switching and power rating. The research plan illustrates the incorporation of both magnetic coupling and DC-link. The new approaches unite numerous input sources. A multiport bidirectional DC-DC converter with single-tapped conversion is proposed. This configuration does not necessitate any further switches. The resultant converter features a straight forward topology and the fewest possible power devices.
