  "textContent": "A method of operating a battery charging circuit for charging a battery is described. The method includes controlling the battery charging circuit to operate in a first mode to output a direct current (DC) current at a first voltage less than or equal to a predefined threshold and controlling the battery charging circuit to operate in a second mode to output the DC current at a second voltage greater than the predefined threshold. In the first mode, the AC-to-DC converter is controlled to regulate a DC link voltage across a DC link capacitor and the DC-to-DC converter is configured to output the DC current at the first voltage. In the second mode, the AC-to-DC converter is controlled to output the DC current and the DC-to-DC converter is bypassed to equalize the DC link voltage with the second voltage.",
