Claim:
1. An electronic device comprising: a plurality of switching elements connected to a power supply; a plurality of specific information storage units provided for the corresponding switching elements and configured to store specific information of respective corresponding switching elements, wherein the specific information storage units include a plurality of driving circuits provided for the corresponding switching element; a processing unit configured to control the switching elements through the driving circuits; and a communication line disposed between the specific information storage units and the processing unit, through which the specific information of the respective switching elements is sent from the specific information storage units to the processing unit, the communication line being single and common to the specific information storage units; and a plurality of drive signal communication lines disposed between the respective driving circuits and the processing unit through which drive signals for driving the respective switching elements are sent from the processing unit to the driving circuits, wherein the driving circuits send the specific information when receiving a predetermined signal from the processing unit through the drive signal communication lines, and wherein the predetermined signal is generated at a higher frequency than a carrier signal for switching on/off the switching elements.
