The bidirectional DC-DC converter comprises six IGBT bridge circuits, a first electric reactor, a second electric reactor, a first positive power input / output end, a second positive power input / output end, a negative power end, a first filter circuit, a second filter circuit and a control panel, wherein the first IBGT bridge circuit, the second IGBT bridge circuit and the third IGBT bridge circuit in the six IGBT bridge circuits are connected with the first positive power input / output end respectively, and the first IGBT bridge circuit is further connected with the first electric reactor; the second IGBT bridge circuit is further connected with the first end of the second electric reactor; the third IGBT bridge circuit is further connected with the first end of the third electric reactor; the first electric reactor is connected with the fourth IGBT bridge circuit in the six IGBT bridge circuits; the second end of the second electric reactor is connected with the first conduction end of the fifth IGBT bridge circuit; the second end of the third electric reactor is connected with the sixth IGBT bridge circuit; and the fifth IGBT bridge circuit, the fifth IGBT bridge circuit and the sixth IGBT bridge circuit are connected with the second positive power input / output end respectively. The bidirectional DC-DC converter solves the problem that the volume of the bidirectional DC-DC converter is large.
Description
technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a bidirectional DC-DC converter and a charger. Background technique [0002] The bidirectional DC / DC converter can convert one kind of DC power into another form of DC power, mainly to realize the conversion of voltage and current. It has been widely used in the fields of renewable energy, power system, transportation, aerospace, computer and communication, household appliances, national defense industry, industrial control and so on. Bi-directional DC / DC can convert the input of high voltage and low current into low voltage and high current through DC converter or transform the input of low voltage and high current into high voltage and low current through converter. [0003] Most of the existing bidirectional DC / DC converters use a large-volume reactor to boost or step-down the output after processing to ensure a large power output to the electrical load.
