Generator, and AC to DC conversion
(San Antonio, TX)
Generator for a AC to DC Cart
I want to power a small electric cart with a generator. I have a Honda 3000 watt generator that I take camping. It's very quiet and has electric start. I want to power an electric golf cart off of the generator, not with golf cart batteries. How could I convert the 120 volt AC to 36 volt DC to replace the batteries?
Dan, our motor man, says:
"I think a 3 Kw generator is too small. This equates to a 4 HP motor. IF it were a decent generator I might say OK but these were not meant for this kind of loading.
I would need to know more about what the intent for the vehicle is i.e. range, speed, etc.
36 VDC will take an industrial charger more than likely. These are generally a 230 volt single phase or 230 or 460 volt 3 phase unit.
If insistent on this setup, I would recommend a 120 V VFD if you can get it in 3 or 4 HP rating and a 3 or 4 HP motor. Geared way down to avoid overload. It can work but the golf cart is going to go real slow."
I'm curious myself, Mike, why don't you want to use batteries?
