Multiport Converter for Micro Grid Application
Sheeja Raphel | Surya Natarajan [2]
Abstract: Nowadays, renewable energy has shared more and more proportions of power demands globally. A new dual source converter is introduced to interface solar PV and fuel cell (FC) sources to a low-voltage dc microgrid. This non-isolated converter topology is efficient, compact and has fewer circuit components with only one inductor compared to the conventional non-isolated dc-dc converters. This topology is suitable for a low-voltage bipolar type dc-microgrid system, where power from both the sources is fed to the bipolar bus of a bipolar type dc microgrid system. This converter is a unidirectional converter with only a single inductor and is well-suited for hybridizing PV source along with FC, UC and Wind sources. Here, a hybrid combination of PV and FC sources are considered. The outputs of this converter are interfaced to a 48 V bipolar type (with_24V) dc microgrid system, where the voltage at the 48V bus is regulated by other sources in the dc micro grid and the voltage at the 24V bus is controlled by the converter along with the other sources in the dc microgrid.
