I have a three phase generator that I am building. I use a motor connected through a shaft to move the generator so I can measure output voltage/current. It has been noticed that if capacitors are connected across each phase the output wattage can significantly be increased. I understand that when a capacitor is resonating with an inductor in series the current goes up dramatically because the impedance approaches zero (in theory). For a parallel LC circuit the impedance goes up dramatically.
So, how does this work into my three phase generator setup? Does it have to do with power factor correction?

Are you sure the output WATTage increases, not just the voltage?
3-ph alternators are quite efficient, meaning it's hard to get more power out without increasing the (mechanical) power in,
unless the electrical LOAD is inductive, in which case pfc action will help WATTs out.
