<P>PROBLEM TO BE SOLVED: To provide an electronic apparatus that can appropriately control a switching element in accordance with characteristics with a simple configuration. <P>SOLUTION: A control device 12 includes an on-driving constant current circuit 121, a voltage limiting circuit 123, a control circuit 124 and a controller 125. The control circuit 124 controls the voltage limiting circuit 123 based on stored characteristic information about an IGBT 110d. Without using two power supplies as before, the on-driving constant current circuit 121 and the voltage limiting circuit 123 can adjust gate voltage of the IGBT 110d. This results in a simplified circuit configuration. The voltage limiting circuit 123 is controlled based on the characteristic information about the IGBT 110d stored beforehand. The IGBT 110d can thus be appropriately controlled in accordance with characteristics. <P>COPYRIGHT: (C)2012,JPO&INPIT |
