Common materials include ferrite cores and powdered iron cores, selected for their magnetic performance and switching frequency characteristics.

A flyback transformer is used in flyback topologies to store and transfer energy. Unlike standard transformers, it requires a core gap to store energy during the "on" cycle before releasing it to the output. It also typically includes an auxiliary winding to power the controller once the circuit is running.

A forward transformer transfers energy directly from the primary to the secondary winding during the "on" period of the switching cycle. Unlike a flyback transformer, it does not store energy in its core; instead, it relies on an output inductor to store energy and maintain current flow when the switch is off.

A power transformer transfers energy between circuits through magnetic coupling and is often used for voltage conversion and isolation. It transfers energy via magnetic flux within the core and does not require a gap.

An isolation transformer provides galvanic isolation between the input and output circuits for safety and noise reduction.

A transformer has two or more windings and transfers energy between circuits, while an inductor stores energy in a magnetic field via a single winding.

Galvanic isolation improves safety, prevents ground loops, and protects sensitive circuits from high voltages. It ensures there is no direct conduction path between the input and output. This is vital for protecting users from mains voltage and preventing noise or surges from damaging low-voltage control electronics.
