Power supplies and transformers are essential components in electrical and electronic systems, providing the necessary voltage and current to power various devices and equipment. These devices are found within everyday items and come in multiple sizes. The design and usage of power supplies and transformers are essential for ensuring various systems' reliable and efficient operation and promoting electrical safety.
A power supply is a device or circuit that converts electrical energy from a source (such as an electrical outlet or a battery) into the appropriate voltage and current required to operate electronic devices. Power supplies are best suited for a myriad of applications, from small consumer electronics to large industrial systems. Power supplies come in various types, including:
Transformers are passive electrical devices that transfer electrical energy between two or more coils (usually wrapped around a magnetic core) through electromagnetic induction. Their fundamental function is to step up or down voltage levels while isolating the input and output circuits. Popular transformer types include:
Power supplies and transformers are distinct electrical devices serving different purposes in a range of applications. Power supplies find applications in various devices and systems, including computers, electronics, telecommunications equipment, and power distribution systems.
Transformers are extensively used in AC power distribution networks for multiple purposes, including stepping up or stepping down voltage levels. They are also used for galvanic isolation and impedance matching.
