coupled inductors
Paired inductors, also called transformer coils or mutual inductors, are electrical elements constitutes of two or more inductances that share one magnetic core. They are designed to transfer energy between circuits while isolating them electrically. Characteristics of this type of inductor include high saturation current, low winding resistance and low leakage inductance The The are widely employed in different fields, such as power supplies and voltage transformation, signal processing, filters, noise reduction. They are the key to making small, efficient electronic devices. Because coupled inductors can couple magnetic fields, they become an essential tool when designing high-efficiency, compact-sized electronic equipment.
