Abstract
A method and apparatus for converting a first power to a second power. In one embodiment the apparatus comprises a power conversion circuit for receiving the first power; and a controller, coupled to the power conversion circuit, for dynamically selecting between a non-interleaved mode and an interleaved mode for operating the power conversion circuit to convert the first power to the second power.
Claims20
Apparatus for converting a first power to a second power, comprising:
- a power conversion circuit for receiving the first power, wherein (i) the power conversion circuit comprises a plurality of power stages coupled to one another in parallel, (ii) each power stage of the plurality of power stages comprises a primary side for receiving an input power and a secondary side to provide an output power generated from the input power, and (iii) for each power stage of the plurality of power stages, power conversion by the power stage is controlled by switching only on the primary side;
- and
- a controller, coupled to the power conversion circuit, for dynamically selecting between a non-interleaved mode and an interleaved mode for operating the power conversion circuit to convert the first power to the second power, wherein only one power stage of the plurality of power stages is used during the non-interleaved mode, and at least two power stages of the plurality of power stages are used during the interleaved mode.
A method for converting a first power to a second power, comprising:
- receiving the first power at a power conversion circuit, wherein (i) the power conversion circuit comprises a plurality of power stages coupled to one another in parallel, (ii) each power stage of the plurality of power stages comprises a primary side for receiving an input power and a secondary side to provide an output power generated from the input power, and (iii) for each power stage of the plurality of power stages, power conversion by the power stage is controlled by switching only on the primary side;
- dynamically selecting, by a controller coupled to the power conversion circuit, a mode for operating the power conversion circuit, wherein the mode is a non-interleaved mode or an interleaved mode, and wherein only one power stage of the plurality of power stages is used during the non-interleaved mode, and at least two power stages of the plurality of power stages are used during the interleaved mode;
- and
- converting, by the power conversion circuit, the first power to the second power utilizing the selected mode.
