1. A circuit control device controlling a semiconductor switching element having a control terminal and driven by voltage inputted to the control terminal, comprising:

  • an input voltage detector that detects inputted voltage to the switching element;

    a desired voltage setting portion that sets a desired value of the voltage to be inputted to the switching element on the basis of predetermined characteristics information of the switching element;

    a control input generation portion connected to the control terminal of the switching element, the control input generation portion generating control input to the switching element such that the value to be detected by the input voltage detector approaches the set desired value.
