Title:
動的多位相動作
Document Type and Number:
Japanese Patent JP4542839
Kind Code:
B2
Abstract:
A control system controls a multiphase output regulator having a regulated DC output and operating at a switching frequency. The multiphase output regulator (52) includes at least two switch arrays to generate individually controllable output phases from an input source (Vin). The output phases combine to form the regulated DC output. The control system comprises a digital controller (64) operable at a sampling frequency, responsive to a sense signal corresponding to the regulated output, that determines a quantity of output phases to generate and that generates drive signals to control each of the switch arrays to generate the output phases. The digital controller controls the drive signals at the sampling frequency and dynamically sets a phase interval between each of the output phases.
