    RC phase shift

    You need to step back about 50 yards, harmonics are not just added to the fundamental. PT=(PF + P 3rd harmonic2 + P 5th Harmonic 2 + P 7th Harmonic 2.........)1/2 I really don't mean to be rude but I think you are completely missing the point here, harmonics do not affect the value of the...

    RC phase shift

    You are missing the point. Harmonics are created in any load that is non-linear. There is no magic crystal. Just non-linear loads. I promise

    RC phase shift

    Hey Kevin, I am not 100% sure that I am getting your question. As far as this quote is concerned maybe I can help a bit. When you are talking about the power grid in North America, the fundamental frequency of the power is 60hz. If you have a non-linear load (i.e. a rectifier) harmonics are...

    5 volt to 3.3 volt

    You should try using a voltage divider. http://hyperphysics.phy-astr.gsu.edu/hbase/electric/voldiv.html

    110v supply

    You guys are thinking too hard. There are two solutions: 1.) If the transformer has "taps" on the winding, you can connect the output to the 85% tap. 110v / 130v = 84% 2.) Get a different transformer.

    v/f control of 3-phase Induction motor

    Sounds good to me, so you just need to program the PWM sequence and build the power circuit. It is going to be a lot of work, I will be interested to see how it turns out :)

    Power Electronic E-book

    Hi there Sutji, I am just going to move your post into the proper fourm :) This seems to be more of a consumer electronics type question, well unless you need the E-Book to run a motor  :o Aaron
