Designing a 28V --> 200V power converter

Click For Summary
SUMMARY

The discussion centers on designing a power converter that transforms 28V DC input to 200V output at 20A, resulting in a power requirement of 4 kW. Participants emphasize the necessity of using an inverter for this conversion and highlight the significant input current of approximately 142.85 amps, which raises safety concerns. Due to the high voltage and power levels involved, the conversation concludes with a warning against inexperienced attempts at such designs, recommending the purchase of pre-built solutions instead.

PREREQUISITES
  • Understanding of inverter technology for voltage conversion
  • Knowledge of high voltage safety protocols
  • Familiarity with power calculations (P=VI)
  • Experience with high power circuit design
NEXT STEPS
  • Research inverter designs suitable for high voltage applications
  • Study high voltage safety standards and practices
  • Explore commercially available 200V power converters
  • Learn about power management in high current circuits
USEFUL FOR

Electrical engineers, power electronics designers, and anyone involved in high voltage circuit design and safety protocols.

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.
