Driving apparatus and switching apparatus

A driving apparatus comprising:

• a gate driving circuit that turns off a first semiconductor element in response to receiving a signal for turning off the first semiconductor element included in the first semiconductor element and a second semiconductor element connected in series between a positive side power supply line and a negative side power supply line;
• a measuring circuit that measures a parameter according to a voltage applied to the second semiconductor element;
• a timing generating circuit that generates a first timing signal if the parameter satisfies a first condition during a time period in which the first semiconductor element is tuned off;
• and
• a driving condition change circuit that, in response to the first timing signal, further decreases a changing speed of a gate voltage of the first semiconductor element than a reference speed during the time period in which the first semiconductor element is tuned off, wherein
• the gate driving circuit turns off the first semiconductor element in also response to that the parameter satisfies a second condition during a time period in which the first semiconductor element is tuned on.
