Classification: CPC H  G | IPC G  H

Claim 7:
8. An electrical power distribution system, comprising:
isolation circuitry comprising an input and an output, wherein the input of the isolation circuitry is configured to be electrically coupled to an output of a direct current (DC) power supply, and wherein the output of the isolation circuitry is configured to be coupled to an input of a first voltage converter and an input of a second voltage converter; and
wherein the isolation circuitry is configured to detect when an additional resistance with a resistance value less than or equal to a resistance threshold level is electrically connected across the output of the isolation circuitry, and, upon detecting that the resistance value that is less than or equal to the resistance threshold level, then reduce a DC voltage level supplied at the output of the isolation circuitry;
wherein a reduction of the DC voltage level supplied at the output of the isolation circuitry does not affect a DC voltage supplied to the input of the isolation circuitry;
wherein the isolation circuitry further comprises:
an alternating current (AC) Wheatstone bridge;
an AC signal generator electrically coupled to first and third nodes of the AC Wheatstone bridge; and
detector circuitry electrically coupled to second and fourth nodes of the AC Wheatstone bridge and configured to (a) detect when a differential peak or root mean square (RMS) voltage or current level across two nodes of the AC Wheatstone bridge exceeds a corresponding threshold level and (b) upon detecting that the corresponding threshold level has been exceed, then generate an electrical signal to cause the DC voltage level at the output of the isolation circuitry to be reduced.
