Isolation Transformers



  • Made of wound copper coils over each other.

  • Can isolate an alternating current from the circuit.

  • Transfers electrical power from the alternating current source (AC) power to the destination device.

  • Isolate the power supply from the powered device for safety reasons.

  • Used to protect against electric shock.

Isolation transformer

  • Provide galvanic isolation to suppress electric noise to delicate electric components.

  • Built with special insulation between the secondary and the primary.

  • Block the DC component transmission in signals from one circuit to another.

  • Allow the AC components to pass their signals.

  • Block any interference that can be caused by ground loop.

Isolation transformer operation

Isolation Transformer operation

  • Designed with acute attention to capacitive coupling between the two windings.

  • The capacitance between the secondary and primary windings would pair AC current from the main winding to the secondary winding.

  • Reduces the coupling significantly of common mode noise.

  • The differential noise can magnetically couple from the secondary to the primary of an isolation transformer.

Applications of isolation transformers

Applications Of Isolation Transformers

  • Used in many different electronic devices that contain circuits

  • that cannot handle or are too sensitive to handle the alternating current directly.

  • Called as power adapters for computer laptops,cell phones and many other electronic devices.

  • Voltage heights supplied to homes and apartments is higher than the required amounts the electronic devices can consume.

Advantages of isolation transformers

Advantages Of Isolation Transformers

  • Increase and decrease alternating currents.

  • Can handle any amounts of voltages necessary.

  • Built to scale depending on the number of times the coils are wound.

  • Reduce electromagnetic and electrical interruptions from other power devices and sources.

  • Improve signal strength in wireless and radio wave communications.
