Surge voltage of 400 V inverter
It is explained that surge voltage is influenced by the switching speed of the inverter. Therefore, can motor burnout be prevented by lowering the carrier frequency?

Answer
No. Although the carrier frequency increases or decreases the switching count, the switching speed is the OFF-to-ON speed of the IGBT element of the inverter.
Therefore, lowering the carrier frequency does not change the switching speed and cannot prevent motor burnout.
