Lithium ion batteries are the subject of much globalattention in the continuing development of advanced energystorage technologies. To date, these batteries offer the bestcombination of energy capacity per gram, cost, and long termcycle stability. However, lithium ion batteries have severaldisadvantages. The materials used in Li-ion batteries arerelatively costly, while capacity is ultimately limited...
When operating in island mode, DC-based microgrid mainly starts up through batteries and bidirectional DC-DC converters. In conventional way, an extra start-up circuit is required to limit the surge current, which not only decreases the efficiency but also increases the cost. In this paper, the generation mechanism of the surge current is analyzed, through which the duty cycle control scheme is proposed...
