Rectifiers work by using diodes to allow the flow of current in one direction while blocking it in the opposite direction. When AC power is input into the rectifier, the diodes ensure that only the positive or negative portion of the AC waveform passes through, resulting in a pulsating DC output. This output can then be further smoothed using capacitors to provide a more constant DC voltage.
There are several types of rectifiers, including half-wave, full-wave, and bridge rectifiers. Each type has its own unique circuit configuration and characteristics. For example, a half-wave rectifier only allows one half of the AC waveform to pass through, resulting in a more pulsating DC output compared to a full-wave rectifier, which allows both halves of the AC waveform to be utilized.
