magnetically coupled filter for harmonic elimination


Joined Jul 3, 2008
can somebody provide some details.. some basics of magnetic filters..
Can you provide some context for what method or device you are talking about. Your question seems too brief and too general to clearly specify what you are asking. At least, I can't figure it out. Maybe someone else can?

In general, harmonic reduction (typically it is reduction and not elimination) involves creating a loss mechanism for the frequencies/harmonics you don't want.

while reading about pwm converters(rectifiers) i came to know about these. . that the RLC filters can be inserted with inductance on the same core as of the transformer winding feeding the conveter. this coupling is thus purely magnetic, but is able to stop the harmonics generated on the secondary side to pass on to primary side.
