BI-DIRECTIONAL DC-DC CONVERTER

摘要

The present invention relates to a bi-directional DC-DC converter (100) comprising: a first terminal (101),a second terminal (103),a transformer circuit (105),a first high voltage side (107) coupled to said first terminal (101), and a second low voltage side (109) coupled to said second terminal (103); wherein said first high voltage side (107) and said second low voltage side (109) are coupled to each other by means of said transformer circuit (105), and said first high voltage side (107) comprises a resonant tank circuit (111) coupled between a first bridge circuit (113) of said first high voltage side (107) and a high voltage side of said transformer circuit (105).Furthermore, the invention also relates to a system comprising at least two such bi-directional DC-DC converters.
