A voltage detecting circuit detects the drain-source voltage VDS of the power FET when the current flows through the power FET. A first overcurrent protection signal generating circuit outputs a first overcurrent protection signal based on the detected drain-source voltage VDS of the power FET. A second overcurrent protection signal generating circuit outputs a second overcurrent protection signal based on a detected rate of increase of the drain-source voltage VDS of the power FET. A control circuit protects the components of the power supply apparatus from overcurrents by turning off the FET when the first overcurrent protection signal and/or the second overcurrent protection signal is generated and output to the control circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Overcurrent protection power supply apparatus","description":"In a high voltage power supply apparatus, e.g., for an electric or hybrid vehicle, current is supplied from a high-voltage DC power source to a load via a power FET.
