Low Frequency Power Transformers are used to step down mains voltage of 230V or 110V to safer voltages like 12V and 6V. The core is made of laminations of a
In Switching Power supplies and RF Circuits, the coils and transformers have many types of cores. Ferrites, Powder Iron, Air and others. These are much smaller and lighter for the
Series and Parallel Transformers Series and Parallel Connections in transformers. Observe the Dot-Polarity. When windings are in parallel the current capacity doubles. When windings are in series the voltage doubles.
