1. Inverter comprising:
input terminals,
output terminals,
controllable switches connected to the input terminals and to the output terminals, and
a control device configured to control the controllable switches such that the controllable switches convert a DC voltage at the input terminals into an AC voltage at the output terminals intended to drive an electric motor, the control device being configured to control the controllable switches according to a first switching frequency and, in response to a temperature of an element of the inverter, to a second switching frequency, the control device being configured to determine the second switching frequency according to an operating point of the motor.
