An efficiency improved single-phase PFC converter for electric vehicle charger applications

Energy management of microgrids

“…Such the existence of multiple conversions may not merely reduce the efficiency of energy utilization, but increase the expenses for grid construction and maintenance, even undermine the system reliability due to the growing number of the converters. To avoid the unnecessary multiple conversion, the concept of the hybrid AC/DC microgrid has been introduced in [21], [27], with discussions around its structure and operation [28]- [30].…”
