and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

But I am not familiar with AC capacitor usage on synchronous generators. This diagram is what I thought was conventional brushless synchronous generator technology:

Perhaps you could post a circuit or block diagram and reference source for the AC caps of which speak.
Thanks,

Yes Bistander,

The Caps usage applies usually to Single Phase Synchronous Generators Exciter Systems.
It is basically an LC Circuit that starts induction on coil by the two small magnets (N-S) in the rotor core...then starts filling up the caps.
The caps once full by faster rotation, energize the coils to then start a reverse process to energize the rotor coils by Induction.
Rotor Coils are shorted by two Diodes to get DC on them and polarize the field in two steady poles.

However, if it works on a Single Phase, it should work for 3 independent phases as well. (just like using three single phase generators exciters with three Caps for each circuit).
But, like you have shown on diagram, the typical 3 phase gen above10 Kw uses Dual Exciter Systems, one with PMG plus a secondary exciter, both in series to add more power to main rotor.

QuoteThe rotor is usually of salient-pole construction as described previously, but in this case the rotor winding is shorted through a diode. On starting, the residual flux in the rotor body induces a small voltage in the stator excitation winding and a current flows through the capacitor.

This current produces two waves of magnetic flux around the air gap of the generator. One wave travels in the same direction as the rotor, to create the armature reaction.

The second wave travels in a direction opposite to the rotor, and induces a voltage in the rotor windings at twice the output frequency. The current circulated in the rotor windings by this induced voltage is rectified by the diode to produce a dc current.

This dc current increases the magnetic flux in the machine, which in turn drives more current through the stator excitation winding, which in turn produces more rotor current. This self-excitation process continues until the flux reaches a point at which the magnetic circuit is saturated, and a stable voltage results.
