Abstract:
A switching device driving apparatus for preventing arm short circuit is provided, including: a first switching device driving unit for receiving a control signal for controlling a first switching device and a second switching device so that they will not turn ON at the same time and outputting an ON/OFF drive signal to the first switching device; and a second switching device driving unit for receiving the control signal and outputting an ON/OFF drive signal to the second switching device, in which the first switching device driving unit outputs a drive signal for increasing the delay of the ON timing of the first switching device with respect to the OFF timing of the second switching device with increase in ambient temperature.
