Designing a 28V --> 200V power converter

Click For Summary

Discussion Overview

The discussion revolves around the design of a power converter that steps up 28V input to 200V output at 20A. The focus includes the technical requirements and safety considerations associated with high voltage and high power circuits.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant requests assistance in designing a circuit for converting 28V to 200V with a significant current output.
  • Another participant suggests that an inverter is needed and questions whether the output is AC or DC, while calculating the input current required.
  • A different participant expresses concern about the high power requirements and questions the feasibility of powering such a circuit from standard mains supply.
  • Another comment warns that the input requirements exceed typical household electrical capacity and advises against attempting the project without experience.
  • Concerns are raised about the safety of the project due to the high voltage and power levels involved.

Areas of Agreement / Disagreement

Participants generally express concern regarding the safety and feasibility of the proposed design, indicating a consensus on the dangers involved. However, there is no agreement on how to proceed with the project, as some suggest seeking ready-made solutions while others question the necessity of the design itself.

Contextual Notes

The discussion highlights the potential dangers associated with high voltage and high power circuits, as well as the lack of experience of the original poster, which raises significant safety concerns.

This topic is too dangerous for you when you have so little electronics experience
I need to design a circuit which takes around 28V of input and outputs the 200v with 20A. Can any one help me.

You need an inverter.
I assume the 28 V is DC, but is the output AC or DC ?
The output will give 20 * 200 = 4 kW.
The input current will be 4000 / 28 = 142.85 amps.
 
What in the world are you building that requires 20 amps and 4 kW of power?? And your input amperage is more than my entire house can pull from the mains! How are you powering the input? You can't just plug this into the wall.

Your input is way above welding machines, and the output is at the level of the mains voltage.
In short: if you have to ask for help, then just don't begin at all.
Buy something ready, but be very careful even with that.

Thread closed temporarily for Moderation...
 
Because of the apparent lack of experience for the OP, especially in High Voltage / High Power circuits, this thread will remain closed as too dangerous.
