Abstract: The present invention provides a three-port converter with magnetic integration and current ripple cancellation. With magnetic integration technology, the number of magnetic rings is reduced, and the number of driving coupling transformers is also reduced, thereby greatly reducing the size and weight of the whole converter; and with a current ripple cancellation branch, the amount of current ripples flowing through the three ports is very low and close to zero. The three-port converter of the present invention reduces the influence of electromagnetic interference and simultaneously saves the filter cost so that the busbar current and battery current are smoother.
