System and method for a power supply

摘要

In accordance with an embodiment, a method of controlling a power supply node includes measuring a voltage of the power supply node, determining a first current based on the measuring, determining a first current and a second current based on the measuring, and summing the first current and the second current at the power supply node. Determining the first current includes operating a first controller having a first bandwidth, and determining the second current includes operating a second controller having a second bandwidth greater than the first bandwidth.

1. A method of controlling a power supply node, the method comprising:
measuring a first signal of the power supply node to form a first measurement stream; decimating the first measurement stream to form a first decimated measurement stream; determining a second signal based on the first decimated measurement stream, wherein the determining the second signal comprises operating a first controller having a first bandwidth; determining a third signal based on the measuring, wherein the determining the third signal comprises operating a second controller having a second bandwidth greater than the first bandwidth; and summing the second signal and the third signal at the power supply node.
