Abstract
A multiple power supply unit includes two DC stabilized power supplies that provide electrical power in parallel to a load, each power supply providing its own operation indication to the other power supply. Each power supply changes a reference voltage used to detect excess current of its own output to the load according to whether the operation indication is received from the other power supply.
