Many here know, with the help of forum members I built an inverter specific for my homemade, neo magnet generator. Works Great ...., having a blast with it ! Hopefully some can help me with another problem. In doing solar, many must be familiar with adding multiple power sources together and the associated headaches involved. I realize right off, this is comparing apples to oranges, but here is my problem in the nutshell. My neo mag "alternator" has 12 coil outputs. I have many coils/core selections to produce many different voltages. I`ll use these simple ones for discussion. A single coil will output 48vac @ approx. 1 amp. Normally I test 2 opposing coils together, as this greatly increases the output. So, ... (2) coils, in series and adding a 5uf run cap will output up to 135vac @ approx. 2 amps under a load of (2) 90 watt flood lights fully lite. Coils can be added in "series" to achieve the required voltage. In most cases they will add up accordingly with some loses. Depending on speed and cap size this can be anywhere from 300 to 500 Hz. So many variables can affect accurate measurements, especially amp readings and precise readings are difficult. So..., adding coils in series works pretty well with some loses,... but adding in parallel is a real issue. In theory, 12 coils should add up to 10 - 12 amps but in reality, I never gets much over 4 or 5 amps. So, while a single coil, (or pair) makes a beautiful sine wave on a scope, add in more and it becomes quite chaotic and always a problem with AC, as with the power grid being a fine example. Now you would think converting to DC and adding a Full Wave Bridge Rectifier to each coil might be an answer. For whatever reason, you can`t use a AC run caps any more before the bridges, so that's a really choppy output right off, but with a 1000uf DC cap at the inverter input you can make it work, which is how I run my inverter. But there is still great loses (amps) and the DC waveform, at the cap, on a scope can appear sawtooth and far from smooth. Hoping some here can help me figure out how to combine my coil outputs without losing so many amps. I will provide answers to all questions any one has as this is getting pretty long. Not looking for anyone to solve my problems, just some ideas and things to try. Thanks
