ABSTRACT This paper presents a proof of concept of a reconfigurable non-isolated DC-DC converter for connecting different energy sources and loads in a DC microgrid. In this chapter, the. . This can be overcome by adding a boost converter with the MPPT control algorithm, which maintains the required DC voltage level for the AC grid inverter. Such a solution is preferred because of the continuous character of the input current. The single-phase source is coupled to a single-phase PFC boost converter, which enhances the input PF utilizing two feedback loops: outer voltage loop control and inner current loop. . This work was supported in part by the Estonian Centre of Excellence in Foundations of the Universe under Grant TK202 funded by the Estonian Ministry of Education and Research, and in part by the research was conducted using the research infrastructure “European Organisation for Nuclear Research”. . In order to reduce the economic costs, enhance the efficiency, and improve the structural stability of microgrids, this paper proposes a novel AC/DC hybrid microgrid structure.
