THREE-PORT CONVERTOR HAVING INTEGRATED MAGNETIC AND ZERO-PORT CURRENT RIPPLE

摘要

A three-port convertor having integrated magnetics and zero-port current ripple, employing a integrated magnetic technology, reducing the number of magnetic rings and driving coupling transformers, and also reducing the volume and weight of the whole machine to a great extent; the three-port convertor enables a current ripple flowing through the three ports to be close to zero by utilizing a current ripple offsetting branch. The three-port convertor reduces electromagnetic interference and filtering cost, thus enabling a bus current and a battery current to be smoother.
