What does a rectifier do?

A rectifier is an essential electrical component used in power conversion systems. Its primary function is to convert alternating current (AC) into direct current (DC). This process is crucial in many applications, such as power supplies for electronic devices, where a stable DC voltage is necessary for proper operation.

The rectification process typically involves the use of diodes, which allow current to flow in one direction only, effectively blocking the reverse flow that is characteristic of AC. By doing so, the rectifier transforms the oscillating AC waveform into a more stable DC waveform.

In various systems, the rectification can be further refined through filtering and regulation to provide clean, usable DC power. This makes the rectifier fundamental in areas ranging from simple power supplies to complex electronic equipment.
