Induction to change output voltage of DC.

Click For Summary
SUMMARY

The discussion centers on the feasibility of using a toroidal transformer to adjust the output voltage of a 12V DC adapter. Participants clarify that wrapping wires around a toroid to create a transformer effect is ineffective because transformers require an AC input, not a DC output. Therefore, the proposed method cannot decrease the voltage or increase the current of a DC supply.

PREREQUISITES
  • Understanding of DC vs. AC electrical systems
  • Basic knowledge of transformer operation
  • Familiarity with toroidal inductors
  • Knowledge of voltage and current relationships in electrical circuits
NEXT STEPS
  • Research the principles of transformer operation with AC inputs
  • Explore methods for adjusting DC voltage, such as using a buck converter
  • Learn about toroidal inductor applications in power electronics
  • Investigate the differences between linear and switching voltage regulators
USEFUL FOR

Electronics enthusiasts, electrical engineers, and hobbyists looking to understand voltage regulation and transformer applications in DC circuits.

I am trying to adjust the output voltage of my 12v DC adapter. Is it possible to wrap the wires of the adapter around a toroid in a closed circuit, and then wrap another wire around the toroid to have the output voltage of this wire decreased, and the current increased?

From your sketch, you are trying to make a transformer after the 12V adapter. That would only work if the adapter had an AC output. You cannot do that with a DC output.
