Title:
BIDIRECTIONAL RESONANT CONVERSION CIRCUIT AND CONVERTER
Document Type and Number:
WIPO Patent Application WO/2017/080143
Kind Code:
A1
Abstract:
A bidirectional resonant conversion circuit and converter. The bidirectional resonant conversion circuit comprises a primary side capacitor (31), three primary side bridge branches (321, 322, 323), three three-port resonant cavities, three transformers (341, 342, 343), three secondary side bridge branches (321, 322, 323), and a secondary side capacitor (36). A first port of each of the three-port resonant cavities is connected to a corresponding primary side bridge branch. A second port of each of the three-port resonant cavities is connected to a grounding terminal of the corresponding primary side bridge branch. A third port of each of the three-port resonant cavities is connected to a corresponding transformer. Two ends of each of the secondary side bridge branches are connected to two ends of the secondary side capacitor, respectively. Each of the transformers is connected to a corresponding secondary side bridge branch, respectively. The bidirectional resonant conversion circuit can realize bidirectional conversion, and a rectifier gain curve is almost identical to an inverted gain curve. The bidirectional resonant conversion circuit is simple to control and highly reliable, can implement current balancing, preventing from adding an additional current balancing circuit, and reducing costs.
