Abstract
An example power converter system includes a multiphase power converter including a plurality of phases and a controller configured to control a steady state operation and a transient state operation of the multiphase power converter. In the steady state operation, the controller is configured to sequentially turn on each of the plurality of phases without phase overlap. In the transient state operation, the controller is configured to turn on at least two non-subsequent phases of the plurality of phases with phase overlap when a load current increase is detected for the multiphase power converter.
Claims20
A power converter system, comprising:
- a multiphase power converter comprising a plurality of phases;
- and
- a controller configured to control a steady state operation and a transient state operation of the multiphase power converter, wherein:
- in the steady state operation, the controller is configured to sequentially turn on each of the plurality of phases without phase overlap;
- and
- in the transient state operation, the controller is configured to turn on at least two non-subsequent phases of the plurality of phases with phase overlap when a load current increase is detected for the multiphase power converter.
A power converter system, comprising:

- and
- a controller configured to control a steady state operation and a transient state operation of the multiphase power converter, wherein:
- in the steady state operation, the controller is configured to sequentially turn on each of the plurality of phases without phase overlap;
- in the transient state operation, the controller is configured to turn on at least two non-subsequent phases of the plurality of phases with phase overlap and prevent phase overlap of subsequent phases;
- and
- in the transient state operation, the controller is configured to turn on the at least two non-subsequent phases at different times.
