Performance Test of 2.5 kW DC Boost Converter for Nanogrid System Applications

The development of power electronics continues to grow rapidly. One type of power electronics is the DC boost converter, which steps up DC voltage to another level. DC boost converters are widely used in many applications; for renewable energy, DC boost converters are very useful for stepping up DC voltage levels from nonconventional energy resources, such as photovoltaics, wind turbines, and fuel cells, to the main system. In this study, we tested a DC boost converter that has been developed to step up 48 V_DC from energy storage to 235 V_DC in the main bus. The DC boost converter will be used in the nanogrids system, developed by TREC and will supply household appliances such as televisions, lamps, laptops, and mobile phones. The performance tests showed between +3% and -1.2% of voltage deviation and 66–98% efficiency.
