BI-DIRECTIONAL ENERGY CONVERSION SYSTEM

摘要

An alternating current (AC) to direct current (DC) high efficiency conversion architecture comprises an AC-to-DC conversion input stage operative to receive an instantaneous AC input, a DC output stage connected to the input stage through an AC link and operative to output a DC power to at least one customer, and an energy storage device used as an energy balancer between the changing power availability at the instantaneous AC input and the constant power requirements of the at least one customer, the energy storage device coupled to both input and output stages stage through the AC link.
