Abstract
A control circuit for controlling a power semiconductor element includes a temperature detection circuit configured to detect a temperature signal of the power semiconductor element, a current detection circuit configured to detect a current signal flowing through the power semiconductor element, a state determination circuit configured to receive the detected temperature signal and the detected current signal, determine a state of the power semiconductor element based on at least one of the detected temperature signal and the detected current signal, and output one or more output control signals indicating the determined state, and a driver circuit configured to control electric power supplied by the power semiconductor element based on the output control signals.
