  "textContent": "This application provides a charging circuit of an on-board charger, an on-board charger, and a charging control method, and relates to the field of on-board charger technologies. A second end of a first power conversion circuit of the charging circuit is connected to a first end of a second power conversion circuit, a high-voltage output end of the second power conversion circuit charges a power battery pack of an electric vehicle, and a first low-voltage output end of the second power conversion circuit supplies power to a low-voltage system of the electric vehicle. The first power conversion circuit is configured to, when the electric vehicle is in a charging mode, convert an alternating current input from a first end of the first power conversion circuit into a direct current and transmit the direct current to the first end of the second power conversion circuit, and is further configured to, when the electric vehicle is in a driving mode, perform direct current conversion on the direct current obtained from the second power conversion circuit and supply a converted current to the low-voltage system. The second power conversion circuit is configured to, when the electric vehicle is in the driving mode, convert a high voltage of the power battery pack into a low voltage, transmit the low voltage to the first low-voltage output end, and output a direct current to the first power conversion circuit.",
