WebEach of these current waves is a harmonic current. Simply: The reason for harmonics occurrence in converters is that they contain power electronics devices, which distorts the current shape from ... WebBut active switches and some other devices will cause the output current to have a lot of harmonics. If there are too many harmonics, the system's loss will go up, and the circuit may stop working. Therefore, putting in a filter to get rid of the harmonics is needed. LCL filters and L filters are the most common types of devices used today.
