What is the role of a rectifier?

A rectifier plays a crucial role in electrical systems by converting alternating current (AC) into direct current (DC). This process is fundamental in applications where a stable DC voltage is required, such as in power supplies for electronic devices, battery charging, and DC motors.

In the conversion process, the rectifier allows current to flow in only one direction, effectively blocking the negative portion of the AC waveform. This results in a pulsed DC output, which can further be smoothed using filters, if needed, to produce a more stable DC supply.

Being able to convert AC to DC is essential for many modern technologies that rely on electronic circuits, making the rectifier a key component in both residential and industrial applications.
