Title:
BIDIRECTIONAL INVERTER CIRCUIT AND BIDIRECTIONAL INVERTER CHARGING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/088256
Kind Code:
A1
Abstract:
Provided are a bidirectional inverter circuit and bidirectional inverter charging apparatus, the bidirectional inverter circuit comprising: a first conversion unit, a second conversion unit, a third conversion unit, and a transformer; the first conversion unit is connected to a direct-current power supply, and the output terminal is connected to the low-voltage side of the transformer; the input terminal of the second conversion unit is connected to the high-voltage side of the transformer, and the output terminal is connected to the input terminal of the third conversion unit; when the direct-current power supply inputs direct current to the input terminal of the first conversion unit, the first conversion unit, the second conversion unit, and the third conversion unit chop, rectify, and invert the direct-current voltage in order to convert it to a first alternating-current voltage output; alternatively, when the output of the third conversion unit is connected to the second alternating-current voltage, the third conversion unit, the second conversion unit, and the first conversion unit perform first rectification, chopping, and second rectification of the second alternating-current voltage in order to convert it to a second direct-current voltage, the second direct-current voltage charging the direct-current power supply.
