I was looking for something else and stumbled on this today. No idea if its junk or what, or even if it would work, but I thought it might be food for thought. http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem& item=120816835281 That isn't the one you need, but it might give some ideas... it is likely a true switching regulator. From auction listing: Specifications Input Voltage: 24V nominal Input range: 20V to 40V Input Current: 30A (max) No-load input current: ≤10mA Output Voltage: DC 13.8V Output Current: 30A Ripple wave: 50Mv Starting delay time: ≤ 2S Maximum Efficiency: ≥90% Insulation resistance: ≥20M Ω (between crust and earth, insulation resistance ≥20M Ω Dimension: 134mm*80mm*50mm Weight: 800gs |

I don't understand. What are you going to use a DC to DC regulator for? The voltage coming out of your stator is AC. |

Sorry, you are correct. You would need to put it though a full wave rectifier. But those are straightforward, that would be the easy part. This is simply the closest device I have seen to the mythical "true switching regulator" for an 1125. Not that it would work, but it's close. And not that I'm even convinced that a proper switching regulator is the solution to the problem. But it's an interesting possibility. |

DC to DC converters are used extensively in spacecraft to boost the DC from solar panels to charge batteries and provide conditioned power for all the subsystems onboard. But that's just one component in a well designed power supply. |
