Abstract

Controller configured to control the pulse widths with respect to periods of a plurality of pulse-width-modulated switching power supplies to regulate the output from each power supply. Controller utilizes feedback information from a previous period to control the pulse width in a next period. The controller stores operating parameters of the switching power supplies and calculates initial pulse widths for an initial period based on the stored operating parameters.

Claims (4)

1. A switching power supply controller, wherein the switching power supply controller controls a plurality of pulse-width-modulated switching power supplies, comprising:

a controller configured to control the pulse widths for each switching power supply to regulate the corresponding output from each switching power supply, the pulse widths for the switching power supplies being defined with respect to periods, and wherein the controller is further configured to control the pulse widths for each switching power supply in a given period based upon feedback information from each switching power supply in a previous period, and wherein the controller is further configured to store operating parameters associated with the switching power supplies and to calculate initial pulse widths based on the operating parameters for an initial period.

2. The switching power supply controller of claim 1 , wherein the operating parameters include capacitances associated with each switching power supply.

3. The switching power supply controller of claim 1 , wherein the operating parameters include an output voltage to be provided by the switching power supply.
