電源。In a switching power supply in which a plurality of switching power supplies operate in parallel for a common load, each has a first switching element that drives a control circuit for input/output voltage conversion, and a switching element that operates when an output abnormality occurs to keep the first switching element in an inoperable state. and a second switching element for causing a transition to , and the operation of at least one of the second switching elements causes the remaining first switching elements whose gate terminals are mutually connected in multiple ways to be in an inoperable state. Switching power supply.
