Hiya Guy's,
Yesterday I went down to town to test out my F&P wind genny stator to find why I wasn't getting the voltage. My mate has been toying with the idea of putting non-polarised fluro caps on each phase of the AC input, now on the test bench with the stator doing 257 rpm we saw 26.2 volts but no amps. Now when we switched the 121 uf of caps shared between the phases the current jumped up to 3 amps . We ended up putting more caps in series with each phase and found a total gain of 4.8 amps for the same rpm on the testbed. Now to prove the theory we put a f&p wind genny online and tried it. Without the caps online we saw around 3 amps in a steady wind but when the caps came online the current jumped up more than double and we were seeing upto 9 amps. My thoughts are the caps are just smoothing the sinewave but it's got me why the current increase. If any blokes can provide some light as just why this is happening we can get some more research done and stop guessing.
Cheers Bryan
