The process of converting Alternating Current (AC) into Direct Current (DC) is known as rectification. This transformation is essential in many electrical systems and applications, especially in power supplies for devices that require a stable and consistent voltage.

Rectification generally involves the use of diodes or other semiconductor devices, which allow current to flow in only one direction. This one-way flow of electricity converts the AC waveform, which alternates between positive and negative values, into a unidirectional flow of DC, which has a constant polarity.

Understanding rectification is crucial for comprehending how electrical systems manage different types of current and ensure that electronic devices receive the appropriate form of power to function reliably. The terminology associated with electrical engineering distinguishes rectification from other processes, such as transformation, which refers to changing the voltage of AC through transformers, or conversion, which is a more generic term that can apply to various types of energy changes without specifying the current type.
