Isolation transformer/Control transformer

An isolation transformer is a type of transformer that isolates one circuit from another. It is used in electrical engineering and electronics to convert voltages from one circuit to another without allowing any direct current to flow between the two circuits. The transformer is designed to block the flow of alternating current while allowing the transfer of power between the two circuits. This is accomplished by using two separate windings on the transformer and connecting them in such a way that the magnetic flux is cancelled out, thus preventing current from flowing between the two circuits. Isolation transformers are commonly used in applications such as medical equipment, power supplies, and industrial automation.
