How a 220V AC divider works?

The 220V AC is then rectified through a few diodes. In this circuit, we used 2 diodes 1N4007 as a half-bridge rectifier. Normally, DC voltage dividers are made with a pair of resistors. Combined, they define the current flowing through the path. We used 9V Zener Diode 1N4739A to limit the voltage to 9V.

What voltage divider is used in a 220V AC circuit?

We used 220V AC main as the input voltage. You may connect fuse for safety reasons. The 220V AC is then rectified through a few diodes. In this circuit, we used 2 diodes 1N4007 as a half-bridge rectifier. Normally, DC voltage dividers are made with a pair of resistors. Combined, they define the current flowing through the path.

Can you turn a 12V DC into 120V AC?

That's what inverters for the car do, to take 12v DC and turn it into 120v AC. Long story short, you can do it, but it's way easier just to start with AC, or convert DC to DC than to try to manufacture AC after its been turned into DC.

Is there a converter?

Yes, there is a converter. There is, in general, some converter that can be made to convert any power source to any other power source. The problems are whether it is (1) affordable and (2) practical. Well, also whether it is "polite" enough once it gets finished converting.

Can a switching converter make 9VDC out of 12-24vdc?

There also exist down-converting switching converters that will make 9Vdc out of 12-24Vdc. They do not dissipate nearly as much heat as the linear regulator, but they are complicated and may broadcast RF noise, as well as putting a "whine" on the output voltage and ground. So the answer is "yes", but the devil is in the details.

What are the types of Transformerless power supplies?

There are two types of transformerless power supplies that are Capacitive & Resistive. Capacitive type is more efficient compared to Resistive Type because of the low heat dissipation and very low power loss. If a circuit requires a very low current of a few milliamperes, such power supply is an ideal solution.
