Abstract
Described are concepts, circuits, systems and techniques directed toward N-phase control techniques useful in the design and control of supply generators configured for use in a wide variety of power management applications including, but not limited to mobile applications.
Claims51
A controller for a power converter, the controller comprising:
- circuitry configured to control the power converter according to an operating mode selected from a plurality of operating modes, at least one operating mode having at least a first operating phase and a second operating phase, the control including:
- turning on one or more first switches of the power converter to implement the first operating phase of the operating mode;
- and
- in response to one or more conditions for transition from the first operating phase of the operating mode to the second operating phase of the operating mode not being met, entering an intermediate operating phase between the first operating phase and the second operating phase by turning on one or more second switches of the power converter;
- and
- in response to one or more conditions for transition to the second operating phase being met, entering the second operating phase by entering a final switch state for a switching cycle.

A method for controlling a power converter configured to operate in a plurality of operating modes, the method comprising:
- turning on one or more first switches of the power converter to implement a first operating phase of an operating mode selected from the plurality of operating modes;
- and
- in response to one or more conditions for transition from the first operating phase of the operating mode to a second operating phase of the operating mode not being met, entering an intermediate operating phase between the first operating phase and the second operating phase by turning on one or more second switches of the power converter;
- and
- in response to one or more conditions for transition to the second operating phase being met, entering the second operating phase by entering a final switch state for a switching cycle.
