Working Principle
En audio toroidal transformer operates on the principle of inducción electromagnética.
- The input audio signal induces a magnetic field in the primary winding.
- This field transfers energy through the toroidal core to the secondary winding.
- The induced current in the secondary winding recreates the audio signal for output, maintaining full electrical isolation.
This process allows the transformer to:
- Isolate circuits and eliminate interference
- Match impedance between devices
- Convert voltage levels as needed
- Preserve the audio signal with clarity and accuracy
