Abstract
A system for switching power supply is disclosed herein. The system may include a controller and a plurality of switching power supplies. The controller may include a processing device. The processing device may determine a monitored current of at least one switching power supply of the plurality of switching power supply, and determine, based on the monitored current, an induction prediction. The processing device may determine, a voltage input prediction corresponding to the at least one switching power supply, and output, by the controller, the voltage input prediction to the at least one switching power supply.
Claims20
A system for switching power supply, comprising:
- a controller;
- a plurality of switching power supplies;
- and
- a processing device operable to:
- determine a monitored current of at least one switching power supply of the plurality of switching power supplies;
- determine, based on the monitored current, an induction prediction;
- determine, a voltage input prediction corresponding to the at least one switching power supply based on the induction prediction;
- and
- output the voltage input prediction to the at least one switching power supply.
A system for controlling a multiphase switching power supply, the system comprising:
- a control loop operable to manage a plurality of switching power supplies;
- and
- a hysteresis window generator operable to dynamically adjust switching thresholds for the plurality of switching power supplies.
A method, comprising:
- determining a monitored current of at least one switching power supply of a plurality of switching power supplies;
- determining, based on the monitored current, an induction prediction;
- determining, a voltage input prediction corresponding to the at least one switching power supply based on the induction prediction;
- and
- outputting the voltage input prediction to the at least one switching power supply.
