Powering trailer with an alternator
This is something that's been kicking around in my head. I've been researching alternators and i've seen 2 that have an output of 370 amps at 1200 rpm. If my math is correct then that is 4440 watts @ ...

THE NEW "HAIR PIN" STYLE OF ALTERNATOR HAS AN UNBELIEVABLE HIGH OUTPUT ESPECIALLY AT IDLE. Some models can put out almost 180 amps at a dead slow idle. These are for AUTOMOBILES, not over the road big rigs or buses, they are not the size of a washing machine.
My issue is with rectifier cooling, the "diodes". With a separate rectifier box, mounted away from engine heat, using adequate heat sinking, and a stator to stator lead AC fan for cooling, this would be one impressive setup. Run THREE stator wires from the alternator stator connections to the box. The box powers the AUXILIARY LOAD, the regular alternator output takes care of the vehicle chassis just like normal. Three 150 ampere 600 PIV rectifiers on the positive and three 150 ampere 600 PIV rectifiers on the negative. One CS 144 parallel bridge with avalanche rectifiers to clamp transients. This is a hell of a system, got a dozen on cruising sailboats. Some have gone circumnavitation (around the world). Throw a couple of electrolytic capacitors in to smooth ripple and wowee. Change the field over to type B add a Cruising 3-stage voltage regulator (totally adjustable) and you have a World Class charging system.
