mmaresco said: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.

milesyoung said: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.
Voltage increase through induction is a process in which a changing magnetic field induces an electric current in a conductor, resulting in an increase in voltage. This phenomenon is known as electromagnetic induction and is the basis for many electrical devices.
When a conductor, such as a wire, is placed in a changing magnetic field, the magnetic field lines will cut across the conductor, which creates a flow of electrons. This flow of electrons results in an increase in voltage, known as an induced voltage, across the ends of the conductor.
The magnitude of voltage increase through induction depends on several factors, including the strength of the magnetic field, the speed of the change in the magnetic field, the orientation of the conductor in the field, and the length and thickness of the conductor.
Yes, voltage increase through induction is a reversible process. If the magnetic field is removed or the conductor is moved out of the field, the induced voltage will decrease and eventually return to zero.
Voltage increase through induction is used in a variety of everyday devices, including generators, transformers, and induction cooktops. It is also used in wireless charging technology, where a changing magnetic field is used to induce a current in a device to charge its battery.
