Voltage Increase through Induction

  1. Mar 22, 2013 #1
    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?
