Title: DRIVING DEVICE FOR SEMICONDUCTOR ELEMENTS
Abstract:
Provided is a driving device for semiconductor elements which is capable of suppressing change of a switching time caused by the driving capability or temperature. The driving device is provided with: a semiconductor chip (10) on which a voltage control type semiconductor element (11) is formed; a temperature detecting unit (21) that detects the temperature of the semiconductor chip (10); a driving-capability adjusting unit (22) that adjusts the driving capability of the voltage control type semiconductor element according to the temperature value detected by the temperature detecting unit; and a timing adjusting unit (23) that adjusts a switching time for the voltage control type semiconductor element according to the temperature value detected by the temperature detecting unit.
