Schematic Power Supply

Schematic Power SupplyThe power supply usually used for experimental work, the power there could be rules ranging from 2 volts to 24 volts with two choices of 60 milliampere currents up to 600 milliampere, then for the stability of the voltage used 3085 CA components, and all the transistors have to wear cooler.

Schematic voltage doubler 6V to 12V

This chart is a way to increase the current 12-volt batteries are just so much more than the original size, or 6-volt batteries 12 volt can be done using the street wearing schematic voltage Doubler, by this means we increase the flow of the 6 volt batteries to be 12 volts, while for output details will be doubled from the original input. When the input is only 12 volts so with the help of this tool could be 24 volts, but its exceptions . Small that it is not always input using this tool could be two-fold from its origin. The main cause could be so because the burden is too heavy and it decreased to 10% to 15%, a clear course. The circuit is only for maximum loads up to 200mA.
The circuit is working normally, if the batteries that will be raised that we put the voltage at the point (A) and point (B), and the results are taken at the point (C) and (D) its schematic view, (C) negative and the point (D) positive. While the function of each existing transisitor was of the kind PNP switching transistor type No. 2N404 and transistors to the second type of ASH-26, then 2SA155 or type / other similar type. Type III AC 128 transistors, and transistors to the IV and V respectively AC 127 and AC 128, for details see component data below,
- Resistors (R1) = 1.2 Ohm 1 / 2 Watt
- Resistor (R2) = 22 Ohm 1 / 2 Watt
- Resistors (R3) = 22 Ohm 1 / 2 Watt
- Resistor (R4) = 470 Ohm 1 / 2 Watt
- Resistor (R5) = 270 Ohm 1 / 2 Watt
- Capacitor (C1 = C2 = 0.022 F/400 Volt (Polyester)
- Capacitor (C3 = C4 = 250F/15 Volt (elco)

Transistors and diodes, respectively see this picture:
voltage doubler 6v to 12 V
A second transistor and PNP transistor type 2N404, ASH-26, 2SA155, duties etc. here multivibrator, the transistor 3 and the converter works as a buffer of low and high impendasi outside the transistors 4 and 5, here transistors 5 and 4 served as the complementary outputs systemntry stage. 3 AC 128 Transistor type transistor his fourth and fifth type AC 127, and diodes to and diodes into a well elco (C3) and (C4) type that is used up your free, original condition can be complied with PIV 100 volts with 500 mA current.

Automatic battery charger

Automatic battery chargerAutomatic battery charger or ABC's highly automated way it works, the battery has discharged its contents, this tool can be used to fill itself automatically and filling in accordance with existing flows, so that damage to the battery cells can be avoided as early as possible, the use of SCR function as SWITCH . Other components are: AC power transformers have figures on the right side as in the scheme below. Click Here!
