Abstract

The invention provides a bidirectional charging inverter circuit, a power supply device and an electric vehicle. The bidirectional charging inverter circuit comprises a rectification filtering module used for converting commercial power into a first DC voltage; the direct current-direct current conversion module is connected with the rectifying and filtering module and used for converting the first direct current voltage into a second direct current voltage in the charging process and converting the second direct current voltage into the first direct current voltage in the power supply process; the direct current-alternating current inversion module is connected with the direct current-direct current conversion module and is used for converting the first direct current voltage into second alternating current voltage; and the control module is connected with the direct current-direct current conversion module and the direct current-alternating current inversion module and is used for respectively controlling the direct current-direct current conversion module and the direct current-direct current inversion module. In the bidirectional charging inverter circuit, the DC-DC conversion module can be used in the charging process and the power supply process, so that the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of charging, and in particular relates to a bidirectional charging inverter circuit, a power supply device and an electric vehicle. Background technique [0002] With the development of charging technology, people hope that the power system of large equipment can not only receive external power input, but also output power externally. However, the rechargeable or power supply system currently on the market is usually realized by two sets of circuits, and the charging circuit and the power supply circuit are independent of each other, so that the charging circuit and the power supply circuit occupy a large space, which in turn makes the overall volume of the power supply system larger , the cost is also higher. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a bidirectional charging inverter circuit, a power supply device and an elec...
