Discussion Overview

The discussion revolves around the feasibility and methods for stepping down 33 kilowatts to either 12 volts DC or 120 volts AC. Participants explore various technical aspects, including the type of equipment needed and the potential applications of such a power conversion.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the specific requirements for stepping down 33 kilowatts, including whether the input is AC or DC and the desired output voltage.
  • Another participant requests further details on efficiency, cooling preferences, and whether a solid-state solution or a motor-generator set is preferred.
  • A third participant expresses skepticism about the original poster's intent, suggesting they may have meant 33 kilovolts instead of 33 kilowatts, and highlights the potential implications of both interpretations.
  • A later reply proposes a method involving a transformer to step down from 33 kilovolts to a lower voltage, followed by rectification and regulation to achieve 12 volts, while noting that such a transformer is typically managed by power companies.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the original intent of the question, with some believing it to be a typo regarding kilovolts, while others focus on the technical requirements for kilowatts. The discussion remains unresolved regarding the specific application and method for the voltage conversion.

Contextual Notes

There are missing assumptions regarding the type of load and application for the 33 kilowatts, as well as the efficiency requirements and cooling methods. The discussion also depends on the clarification of whether the original poster meant kilowatts or kilovolts.

Is there a product that will step down 33Kw to 12v DC? or 120v ac?

Do you want to step down 33 kilowatts ( ac or dc, and at what voltage?) to 12 volts dc (and 2,750 amps) or 120 volts ac (and 275 amps)? Please provide details. What efficiency is needed? Air cooled or water cooled? Would you prefer solid state or a motor-generator (MG) set?

Forget that, I want to know what he plans on using 33 KW for, though I have the disappointing feeling that he meant 33 KV but this also has a lot of potential (pun intended).
 
Assuming that was a typo and you meant 33 KV, you get a 33 KV to 110 volt or 18 volt transformer and you then rectify the 18 volts and regulate the output to 12 volts using a voltage regulator.

However, this is a serious transformer and usually the power company does the hard work for you out in the street. They bring the power to you as a much safer 110 volts and you can then put whatever transformers you like on that.
