Pulse transformers are a type of transformer that is specifically designed to handle high frequency signals. They are commonly used in electronic circuits for applications such as signal isolation, impedance matching and voltage level shifting. The primary and secondary windings of a pulse transformer are designed to have a low inductance to allow for fast rise and fall times of the signals. Pulse transformers are often used in power electronics, telecommunications equipment and medical devices. They play a critical role in the efficient and reliable operation of various electronic systems.
