Discussion Overview

The discussion revolves around converting AC voltage from a small engine's stator to DC for use in a Cushman scooter, specifically for powering lights and charging a battery. Participants explore methods and components that could facilitate this conversion.

Discussion Character

  • Technical explanation
  • Exploratory

Main Points Raised

  • One participant suggests using a rectifier to convert AC to DC, noting that the DC output will depend on the AC input voltage.
  • Another participant mentions the possibility of using switching supplies to achieve the desired conversion.
  • A different participant points out that the engine's alternator likely has a battery charging system and inquires about the voltage of the battery in the scooter to assess compatibility.

Areas of Agreement / Disagreement

Participants generally agree on the need for a rectifier and the potential use of switching supplies, but there is no consensus on the specifics of the battery voltage compatibility or the best approach to take.

Contextual Notes

Participants have not clarified the specific voltage requirements for the scooter's battery or the exact characteristics of the AC output from the engine's stator, which may affect the conversion process.

Hello,
I have a small 9hp engine with electric start and a stator that puts out between 5-18 volts ac, it only has one wire coming out and would like to convert it to dc to run lights and charge my battery on a cushman scooter. any help would be appreciated...

What you're looking for is a rectifier. Remember that the Vdc out of the rectifier will be a function of the ac input. It's usually easier to transform the ac going into the rectifier to a value that will give you the desired dc output than to convert the output dc into another value.
 
denni is right, you can get tons of switching supplies (some rather small) that can probably do the task you want.
 
Your alternator is electric start, so it must have a battery and a battery charging arrangement in it already.

Do you know what voltage this battery is and what voltage is the battery in your electric scooter?

If they are the same voltage, it may be possible to borrow some of this power to charge your scooter.
