Classification: CPC B  H | IPC B  H

Claim 0:
1. A system comprising:
a first direct current (DC) power supply comprising a first generator and a first rectifier circuit;
a second DC power supply, wherein a first output of the first DC power supply and a second output of the second DC power supply are commonly coupled at a common bus point;
a first current sensing device coupled between the first output of the first DC power supply and the common bus point;
a first generator controller configured to:
receive a first current signal from the first current sensing device;
analyze the first current signal to determine a first voltage droop value based on the first current signal; and
operate the first DC power supply to reduce a first voltage output of the first DC power supply by the first voltage droop value;, wherein the determining the first voltage droop value comprises:
filtering, by an electronic filter, the first current signal;
determining a voltage droop function;
inputting the first current value into the voltage droop function to determine the first voltage droop value;
determining, by the first generator controller, a maximum voltage droop value;
comparing the first voltage droop value to the maximum voltage droop value; and
setting the first voltage droop value to the maximum voltage droop value based on a determination that the first voltage droop value exceeds the maximum voltage droop value.
