Abstract
A power converter includes a semiconductor element disposed on a substrate, a thermistor element for detecting the temperature of the substrate, the thermistor element being disposed on the substrate, a current detection resistor having one end connected to a ground side node and another end that is grounded, a first voltage detection unit configured to detect a first potential at the other end of the current detection resistor and a second potential at the ground side node, and output a first detection signal, a control unit configured to control the semiconductor element based on the first detection signal, a temperature detection resistor having one end that is connected to a reference potential and another end that is connected to a detection node, and a temperature detection unit configured to detect a temperature based on a third potential at the detection node, and output a temperature information signal.
