Claim Text:
1. A driving system for driving a switching element, the driving system comprising: a first controller installed in a first system and configured to control the switching element; a temperature measuring module installed in a second system different from the first system and configured to measure a temperature of the switching element, and output a first signal representing the measured temperature of the switching element; a state determining module installed in the second system and comprising a first comparator configured to: compare the measured temperature of the switching element with a first threshold temperature based on the first signal; determine whether the switching element is in a specified temperature state based on a result of the comparison by the first comparator, and output a second signal representing a result of the determination to the first controller; a communication medium that communicably connects between the first system and the second system, the second signal output from the state determining module being transferred to the first controller via the communication medium, the first controller being configured to determine how to drive the switching element based on the second signal transferred thereto via the communication medium; a second comparator installed in the second system and configured to compare the measured temperature of the switching element with a second threshold temperature based on the first signal; and a second controller installed in the second system and configured to locally disable drive of the switching element if the measured temperature of the switching element is lower than the second threshold temperature based on a result of the comparison by the second comparator.
