Abstract
A power supply system is capable of feeding electric power from a power adapter to a plurality of load devices. The power adapter includes a primary core; and a primary coil wound around the primary core for serving as a output port of the power adapter to output an alternating current. The load devices include secondary cores for simultaneously forming magnetic circuits between the primary core and the load devices; and secondary coils wound around the secondary cores for feeding output power to the load devices. The primary core has two pairs of protrusions, and the secondary cores are arranged on opposite sides of the primary core in such a manner that the primary core lies between the secondary cores to feed electric power simultaneously to the load devices.
