What are Rectifiers?
Rectifiers are semiconductor devices or systems that convert AC electricity into DC electricity. They are fundamental in providing steady and regulated power for a wide range of electronic and industrial applications. Depending on the configuration, rectifiers can be:
- Half-wave rectifiers: Convert only one half of the AC waveform.
- Full-wave rectifiers: Utilize both halves of the AC signal for improved efficiency.
- Bridge rectifiers: Offer higher output and lower ripple for more demanding applications.
Rectifiers are widely used in power supplies, battery charging systems, DC motor drives, and renewable energy converters.
