Inverter
The Inverter as well as normal electric machines has an input current containing har-
monics because the Inverter converts AC into DC. The output current of the Inverter is
comparatively high. Therefore, the ratio of harmonics in the output current of the
Inverter is higher than that of any other electric machine.
