Galvanically isolated MPPT DC/DC converter for PV string tied to industrial DC microgrid

Abstract

This paper concerns to the research project where experimental 600VDC microgrid that simulates industrial assembly line is built. The purpose of the project is to improve efficiency of manufacturing robotic assembly line and to integrate alternative energy sources. As there is hard to find on the market DC/DC MPPT converter that could be tied to 600VDC microgrid, this paper describes the design of such MPPT DC/DC converter and it main challenges like efficiency. Simulation and experimental results are given in the paper.
