Assignee: OMRON CORPORATION
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 4:
5. A power supply apparatus comprising a terminal protection voltage detector circuit,
wherein the terminal protection voltage detector circuit is configured to protect a terminal block having a plurality of output terminals in a power supply apparatus,
wherein the terminal protection voltage detector circuit comprises:
a current detector configured to detect a plurality of output currents flowing from the power supply apparatus to a plurality of loads via a plurality of output terminals,
a first comparator configured to compare a sum of the plurality of detected output currents with a predetermined first threshold, and output a first comparison result signal when the sum of the plurality of output currents is larger than or equal to the first threshold,
a second comparator configured to compare a maximum value of the plurality of detected output currents with a predetermined second threshold, and output a second comparison result signal when the maximum value is equal to or larger than the second threshold; and
a current stop circuit configured to stop a current from flowing from the power supply apparatus to the plurality of output terminals based on the first comparison result signal or the second comparison result signal, and
wherein the power supply apparatus includes:
an inverter circuit configured to convert DC power into AC power; and
a rectifier circuit configured to convert AC power from the inverter circuit into DC power, and
wherein the current stop circuit stops operation of the inverter circuit.
