Are you familiar with direct current (DC) and alternating current (AC)? You deal with them all the time. Batteries usually provide DC current, while all your electric wall outlets supply AC current. But many of your electronic devices use DC power. How do these DC devices work when the supply power is AC? There must be some conversion occurring, right? That's where rectifiers come in.
Why They’re Important
AC-to-DC converters are either built inside devices or made part of the power cords. Check the adapters of your laptop, phone charger, or other appliances; most of them will show the input as AC and output as DC.
Now what does a rectifier do? In the figure above, Graph 1 depicts an AC waveform. Voltage is on the
In addition to AC-to-DC transformations, rectifiers have many other uses as well. Take a look:
