Abstract (en)
[origin: WO2022159927A1] Methods and apparatus for converting power using a multi-output switched- mode power supply (SMPS) coupled to a multi-cell-in-series battery, such as charging a two-cell-in-series (2S) battery using a dual-output three-level buck converter coupled thereto, or using a multi-input SMPS circuit receiving power from a multi-cell-in-series battery. One example power supply circuit generally includes a switched-mode power supply circuit having an input node and an output node, a battery comprising multiple cells connected in series, a charge pump circuit having a first terminal and a second terminal, the second terminal of the charge pump circuit being coupled to the battery, a first switch coupled between the output node of the switched-mode power supply circuit and the first terminal of the charge pump circuit, and a second switch coupled between the output node of the switched-mode power supply circuit and the second terminal of the charge pump circuit.
