inductive spiking as a viable electricity generation method?
i have made a multi phase alternator to be used in a permenant magnet rotor setup , where the rectified DC output is 3V on average at the operating rate of rotation, as you can see in this video
however, the AC wires leading to the rectifier had exposed solder joints, and while holding the positive and negative DC output, i received an electric shock to my fingers ...
this is a picture of the alternator https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-ash3/523686_10150938016016197_502061196_11628304_387425437_n.jpg
as you can see, it is a 5 phase alternator (notice the 5 brown AC output wires) , with 3 coils in each phase for a total of 15 coils (most obvious by the T-shaped structure potruding from each coil) ... the coils have 400 turns each, and they have basically an iron core... i am estimating their inductance values to be in the millihenry range
i also have a total of 4.7 μfarad capacitance in parallel with the DC output
after abit of testing, i have found that if i short out certain pairs of AC phases , the DC output would jump to ~12V before falling down back to slightly below 3V , and by releasing the short, the DC voltage jumps again before falling... and by continuously shorting and releasing the phases, the high voltage can be mantained...
this suggests that the sudden change in current resulting from the short was enough to cause a flyback voltage spike, and fill the capacitors to 12V
bear in mind that the only thing i have ever connected to the DC output was this multimeter that i have used in the video...
i am thinking of using diodes to 'switch' the shorting between the phases, hopefully this will sustain the high voltage when a heavier load is applied across the DC ouput?
