How can I get 12 volts

Fans make anything at home know what to check for devices operating efficiency of a low voltage of 12 Volt constant or variable component is required so these devices powered voltage. In this article I will tell you what are the options for such a strain.

Important. Before proceeding to an analysis of options for obtaining a voltage of 12 volts to say a few words about power. Even if you get the desired voltage, but its source is a low-power, it does not even start. For example, let's compare the power supply unit and the vehicle battery. In both cases, the source is output at 12 V, but the power supply will give the order of 20 amps, and battery is capable of delivering up to 200 A. From this it appears that the battery will launch the vehicle and the power supply just burn when you try to start the car (because when you start the car consumes huge amounts of energy).

So, a brief digression is over, we go further.

Options for receiving a DC voltage

Thus, perhaps the most extraordinary way to get 12 volts is an assembly of the following construction of 8 batteries connected in series:

After completing connection of batteries by the algorithm with the first plus the second disadvantage, one can obtain voltages of 6, 9, 12 volts. Under this option, keep in mind that all of the batteries have to be "fresh" if at least one of them will be discharged, the capacity of the whole structure will be reduced.

When connecting the batteries, you will add up the voltage and amperage will remain unchanged.

If, however, you will need to connect a device that draws more current than the design produces 8 batteries, you will need to do exactly the same garland and connect it with the first parallel connection.

Thus, you will have the voltage of 12 volts, but the current strength will double.

Using PSUs

Much more traditional one, and the best producing 12 volts is the use of ready-made power supplies that are powered by 220 volts and output voltage is rectified and stabilized at 12 Volt.

When choosing such a power supply is necessary to consider its capacity.

Also, such a power supply can be assembled independently, below is a diagram of a simple charger where AC voltage of 220 V is reduced to 12 volts and then through the diode bridge rectified and smoothed condenser. And regulates the transistor using the as-built resistor.

If you need a 12 Volt recess, in this case a conventional step-down transformer.

Note. When using any source note is the fact that they must have a power reserve of at least 30%. Then this source will function reliably without overheating.

conclusion

It's all available options for producing 12 volts at home. If the article has been helpful, you will appreciate it Like. Thank you for your attention!
