Abstract
A semiconductor device comprises a driver provided for a semiconductor element having a control electrode to which a drive voltage is applied, the semiconductor element being switched between the conduction state and the non-conduction state based on the drive voltage, the driver operative to apply the drive voltage to the control electrode; a detector operative to supply a voltage detection signal oscillating at a certain frequency to the control electrode to detect a first voltage having a certain relation to a voltage applied to the semiconductor element; and a controller operative to control the detector based on the first voltage detected at the detector.
