PV/battery hybrid energy system via a double input DC/DC converter for dynamic loads

Analysis and experimental verification of a multi‐input converter for DC microgrid applications

“…In (26), f s denotes the switching frequency, N P the number of paralleled switches, V DS the drain-source voltage, I D the drain current, t on and t off turn-on and turn-off switching transitions, and C oss the parasitic output capacitor. Note that calculation procedures for t on and t off based on data-sheet parameters can be found in [31].…”

“…This work focuses on a deep analysis and an experimental verification of a non‐isolated bidirectional MIC that can construct a DC microgrid having a hybrid power system. The primary version of this MIC with a coupled inductor was first proposed in [25] to combine a fuel cell and an ultra‐capacitor for dynamic loads through a simulation study; then its practicality was shown via another simulation study creating a photovoltaic (PV)–battery hybrid system in [26]. Although these studies present analyses in a fundamental level, they neither provide experimental results to verify these analyses and show the practicality of the MIC for a hybrid power system nor explore the effect of the source voltage levels and duty cycles of switches on the conversion efficiency which is crucial when it comes to an application.…”
