How Ac can converted into Dc
Answers
Answer:
Explanation:
Converting AC to DC is far easy than converting DC to AC.
First of all you need a transformer which transform 220v and make it a low voltage AC wave.
Remember:
Transformer only work on AC, Transformer size depends on core material, voltage rating, current, and copper quality.
After step down to a smaller voltage you need to stop polarity changes and also stop those frequency as DC pass in one direction and has 0 frequency.
How to do it?
For this you need diodes. You need to connect 4 diodes as a bridge.
Then what to do?
Here is a very good way to rectify this wave. Lets add a electrolytic capacitor with a higher value. Capacitor work as a tank. It’s has a ability to store charge.
What is going on in this circuit?
When those first round of DC wave comes up capacitor get charged wave comes to zero instantly but capacitor discharge slowly, so in the output line voltage always presented. Filter capacitor fills those gaps as the don't get discharge very fast. It’s smoothly generates DC.
Now if you want to make it more straight then add a voltage regulator.
This can be achieved by a zener diode too. Zener diode is a type of diode that act as same as diode but has a condition. It has limitation at a specific voltage (this voltage is a rating of zener diode). If the voltage reach the limitation it will pass the flow in bi directional. It will not act as diode in this time.
Best way to use regulator. This regulator is IC inbuilt with those zeners and many components. It will regulate the voltage and block unwanted spikes.
Answer:rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification, since it "straightens" the direction of current
