摘要： A power supply system includes at least two power supply devices that supply a current to a load. Each of the at least two power supply devices includes a converter configured to generate a current that is to be supplied to the load, an FET that is connected in series between the converter and the load, a gate voltage monitoring circuit configured to monitor whether a gate voltage of the FET has fallen below a predetermined first reference voltage, and an alarm generation circuit configured to generate an alarm according to a result of monitoring by the gate voltage monitoring circuit.
