Switching element control circuit and power module

A switching element control circuit for controlling an ON/OFF operation of a switching element which includes a first electrode, a second electrode, and a third electrode, the switching element control circuit comprising:

• a third electrode voltage control part which controls a third electrode voltage for controlling the ON/OFF operation of the switching element;
• a temperature detection part which detects an operation temperature of the switching element;
• a memory part which stores information including an initial threshold voltage of the switching element and an initial temperature of the switching element when the initial threshold voltage is measured, and information relating to a temperature characteristic of a threshold voltage of the switching element;
• and
• a threshold voltage calculation part which calculates a threshold voltage at a time of operating the switching element based on information including the operation temperature of the switching element detected by the temperature detection part, the initial threshold voltage, and an initial temperature of the switching element when the initial threshold voltage is measured, and information relating to the temperature characteristic of a threshold voltage of the switching element, wherein
• the third electrode voltage control part controls the third electrode voltage based on the threshold voltage at the time of operating the switching element calculated by the threshold voltage calculation part at the time of bringing the switching element into an ON state.
