Abstract
Official abstract text for this publication.
A system and method are provided for regulating a voltage at a load. A target current is obtained and a number of regulator phases needed to provide the target current to a load is computed based on an efficiency characteristic of the regulator phases. The regulator phases are configured to provide the target current to the load. A multi-phase electric power conversion device comprises at least two regulator phases and a multi-phase control unit. The multi-phase control unit is configured to obtain the target current, compute the number of the regulator phases needed to provide the target current to the load based on the efficiency characteristic of the regulator phases, and configure the regulator phases to provide the target current to the load.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: obtaining a target current; computing a number of regulator phases needed to provide the target current to a load based on an efficiency characteristic of the regulator phases; and configuring the regulator phases to provide the target current to the load, wherein a first regulator phase is configured to couple a first current source to the load to provide a first portion of the target current, and a second regulator phase coupl…
