Thanks guys,
I was trying to assess the effect on a rectified AC capacitive dropper waveform after flowing it through 2 identical common mode chokes wired in parallel. Both with an individually lower current rating than the total cct current being flowed, though in parallel within their rated specs. I was trying to determine how proximity and orientation would effect the intended output waveform. I was hoping that I could orient in a position in such a way that the field lines wouldn't cancel, but compound (if anything), but I've read that inductors in parallel reduce total inductance, so I'm just not sure I'm comprehending (it seems the equation doesn't have any variables for proximity or orientation, the things I thought would have the greatest impact on inductance). I figured if I could determine the most favorable positions and/or why, that I'd be able to then orient inversely for a minimal interaction.
When I simulate inductors in parallel in LTspice, it seems the program accounts for proximity. The closer I place the parallel inductors to each other, the less filtering I notice. I've run some simulations and used 100mH as my inductor size, but I've only 0.35A rated inductors and the cct sim was for 0.5A, so thus what sparked my question.
Also, I'm curious about EMI? If I were designing an RC car or drone, what kind of shielding or proximity to antennas ect should I be aware of? If the Hz of the waveform going into the inductor is different than the radio frequency used for wireless commands, I shouldn't have interaction, or should I? What signals are most susceptible to inductor noise, or maybe there isn't a generic correlation to be had? Can you wrap an inductor in aluminium foil and mitigate EMI? Will inductors induce a charge inside capacitors if placed within close proximity?
