Analog finter design for harmonics reduction

  1. Mar 31, 2009 #1
    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.?)
