Voltage Increase through Induction

AI Thread Summary
To increase voltage from 12V to approximately 400V, a DC-DC step-up converter is necessary, as transformers only function with AC due to the requirement of a time-varying magnetic field. The project involves using a 0 A.W.G. braided copper wire for the initial winding and an 8 A.W.G. wire for the output. Given the high output voltage, the design and construction of such a converter can be complex and potentially hazardous, especially for someone new to the field. It's crucial to understand the application and safety implications before proceeding. Proper guidance and expertise are recommended for this type of project.

I am new to the field and have stumbled across an issue. The current project I am working on is requiring me to calculate how many windings I need to increase voltage in a system from 12v to ~400v. The Initial winding will be fed from a 0 A.W.G. braided copper wire and the outgoing feed will, ideally, be a 8 A.W.G. braided copper wire. Is there a formula that can enable me to acquire this calculation.

Welcome to the PF.

If you are talking about AC, then the voltages ratio with the number of turns for each winding.
 
The system would run on DC.
 
A transformer sadly only works for AC since you need a time-varying magnetic field for electromagnetic induction.

For what you're asking, you need a DC-DC step-up converter.

Yeah, and from the sound of the size of wire and the high output voltage, this will be one BIG DC-DC converter.

@mmaresco -- since you say that you don't have experience with this, you are not going to be able to design and build such a converter. Not to mention that your 400V output voltage will make the whole setup quite dangerous. Why are you being asked to look into this? What is the application?
 
Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
