Matrix regulation control
A power provision device including: a load element; a power supply plane configured to provide current to the load element; a plurality of power supply elements configured to provide current to the power supply plane; wherein each power supply element is configured to provide a current corresponding to a plurality of selectable current values to the power supply plane via an individual power connection; and wherein each of the plurality of power supply elements comprises a controller configured to control the power supply element to: transmit information to and receive information from other power supply elements of the plurality of power supply elements; select a current value based on information received from other power supply elements, wherein the information includes a current supplied by the other power supply elements; and output a current corresponding to the selected current value.
1 . A power provision device comprising:
a load element;
a power supply plane configured to provide current to the load element;
a plurality of power supply elements configured to provide current to the power supply plane;
wherein each power supply element is configured to provide a current corresponding to a plurality of selectable current values to the power supply plane via a power connection; and
wherein each of the plurality of power supply elements comprises a controller configured to control the power supply element to:
transmit information to and receive information from other power supply elements of the plurality of power supply elements;
select a current value based on information received from other power supply elements, wherein the information includes a current supplied by the other power supply elements; and
output a current corresponding to the selected current value.
2 . The power provision device of claim 1 , wherein the plurality of power supply elements are disposed on a single plane such that each power supply element has at least one neighbor power supply element;
wherein a neighbor power supply element is a power supply element that is orthogonally and/or diagonally adjacent.
3 . The power provision device of claim 2 , wherein the plurality of selectable current values comprise a range of stepped current values;
wherein the current values are stepped by a predetermined interval.
4 . The power provision device of claim 3 , wherein the current value is selected by each power supply element such that it is within a predetermined number of intervals of each neighbor power supply element.
5 . The power provision device of claim 4 , wherein the current value is selected by each power supply element such that it is at most one interval higher or lower than the current value provided by neighboring power supply elements.
6 . The power provision device of claim 3 , wherein a minimum selectable current value represents a maximum efficiency; and
wherein a maximum selectable current value represents a maximum current output.
7 . The power provision device of claim 2 , wherein each power supply element comprises a plurality of input ports for receiving the information from neighbor power supply elements;
wherein the number of input ports corresponds to a maximum number of neighbor power supply elements.
8 . The power provision device of claim 7 , wherein each power supply element has up to six neighbors.
9 . The power provision device of claim 8 , wherein when a power supply element has less than a maximum number of neighbors, the power supply element is configured to select a current value based on a maximum current value for each input port that is not connected to a neighbor power supply element.
10 . The power provision device of claim 7 , wherein the information is transmitted and/or received to and/or from neighbor power supply elements of neighbor power supply elements based on the information that is being transmitted and/or received.
11 . The power provision device of claim 1 , wherein the information includes at least one of: temperature data; current output data; and output voltage data.
12 . The power provision device of claim 1 , wherein the current value is selected based on a comparison between a voltage feedback signal and a predetermined target output current;
wherein the voltage feedback signal is received by the power supply element from a voltage feedback connection between the power supply element and the power supply plane or load element.
13 . The power provision device of claim 7 , wherein each power supply element has up to four orthogonally adjacent neighbor power supply elements.
14 . A method of configuring a current output for a power supply element that is part of a plurality of power supply elements of a power provision device, the method comprising:
transmitting and receiving information from other power supply elements of the plurality of power supply elements; and
selecting a current value based on the received information, wherein the information includes a current supplied by the other power supply elements;
outputting a current corresponding to the selected current value.
15 . The method of claim 14 , wherein the information is transmitted to and received from neighbor power supply elements;
wherein a neighbor power supply element is a power supply element that is orthogonally and/or diagonally adjacent to the power supply element.
16 . The method of claim 15 , wherein the information comprises data representing a state of the power supply element and a request to increase or decrease a current output by the neighbor power supply elements.
17 . The method of claim 16 , wherein the current output by the power supply element is limited by the current output by the neighbor power supply elements.
