1. A semiconductor module comprising:
a first terminal configured to be fed with a first potential;
a second terminal;
a third terminal configured to be fed with a second potential lower than the first potential;
a first switch connected between the first and second terminals;
a second switch connected between the second and third terminals;
a first driver configured to turn on and off the first switch; and
a second driver configured to turn on and off the second switch,
wherein
the first driver is configured to set, based on a voltage fed to the second terminal, an inhibition period of time during which the first switch is inhibited from being turned on, and
the first driver is configured not to include, in the inhibition period of time, a period of time in which the voltage fed to the second terminal is a negative voltage.
