Claim 14:
15. A system comprising:
an alternating current to direct current (AC-DC) conversion circuit coupled to an AC power supply that converts AC power to DC power;
a plurality of power transmitters, each configured to output power to a corresponding current loop of a plurality of current loops, wherein each power transmitter is configured to determine whether a current level on the corresponding current loop passes a safety check within a predetermined time interval since a determination that the current level was not within a safe range, and to control connectivity of power to the corresponding current loop depending on whether the safety check has or has not passed within the predetermined time interval; and
a plurality of isolation circuits each of which is coupled between the AC-DC conversion circuit and a respective one of the plurality of power transmitters.
