Inverter
The Inverter as well as normal electric machines has an input current containing harmonics 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.
