Designing a 28V --> 200V power converter

AI Thread Summary
Designing a circuit to convert 28V DC to 200V with a 20A output requires an inverter capable of handling 4 kW of power. The input current calculation reveals a demand of approximately 142.85 amps, which exceeds typical household electrical capacities. Concerns arise regarding the safety and feasibility of such a high-power project, especially given the OP's apparent lack of experience in high voltage and high power circuits. The discussion emphasizes the risks involved and suggests considering pre-built solutions instead. Due to these safety concerns, the thread has been temporarily closed for moderation.

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.

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.
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
