Analog finter design for harmonics reduction

AI Thread Summary
The discussion focuses on designing an analog filter to reduce harmonics in a 12VDC-12VAC inverter that currently outputs a perfect square wave. The user seeks guidance on how to filter out harmonics while preserving the fundamental frequency. Questions arise regarding filter types, such as Butterworth or Chebyshev, and the importance of filter order in determining performance. The context of the project remains unspecified, prompting inquiries about its purpose. Effective filtering strategies are essential for improving the inverter's output quality.

Hi,

I have build an 12VDC- 12VAC inverter using a square wave gate signal for my power MOSFETs.
My output is perfect square wave and now i want to clear the harmonics except the fundamental. I am not sure how can i design the analog filter that can filter the harmonics except the fundamental.
Any help would be appreciated. Thanks

Tell us what you know about filters so far. What does the order of the filter determine? How would you go about choosing the type of filter (Butterworth, Cheby, etc.)? What is the context of this project? (school/work/hobby/etc.?)
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
