How to Make a 50 Watt Small Homemade Inverter – A school Science Exhibition project
A 50 watt inverter may look truly trifling, yet it can fill some helpful needs to you. At the point when outside, this little power house can be utilized for working little electronic devices, welding iron, table top radios, brilliant lights, fans and so forth.
We should figure out how to manufacture this custom made 50 watt inverter unit, starting with a brief portrayal in regards to the circuit chart and its working:
Circuit Portrayal
The circuit may be comprehended with the accompanying focuses:
Alluding to the figure, transistors T1 and T2 alongside the other R1, R2, R3 R4, C1 and C2 together shape a straightforward astable multivibrator (AMV) circuit. A multivibrator circuit fundamentally is made out of two symmetrical half stages, here its framed by the left and the right hand side transistor stages which lead in pair or in straightforward words the left and the right stages direct then again in a sort of an interminable "movement", creating a consistent flip failure activity.
The above activity is capable of making the obliged motions for our inverter circuit. The recurrence of the swaying is straightforwardly relative to the estimations of the capacitors or/and the resistors at the base of every transistor.
Bringing down the estimations of the capacitors builds the recurrence while expanding the estimations of the resistors diminishes the recurrence and the other way around. Here the qualities are picked in order to deliver a steady recurrence of 50 Hz.
Perusers, who wish to modify the recurrence to 60 Hz, might effortlessly do it by simply changing the capacitor values properly.
Transistors T2 and T3 are put at the two yield arms of the AMV circuit. These are high increase; high current Darlington combined transistors, utilized as the yield gadgets for the present arrangement.
The recurrence from the AMV is sustained to the base of T2 and T3 on the other hand which thusly switch the transformer optional winding, dumping the whole battery power in the transformer winding.
This outcomes in a quick attractive prompting exchanging over the transformer windings, coming about the obliged the mains voltage at the yield of the transformer.

Parts Required
You will require the following components for making this 50 watt homemade inverter circuit:
R1, R2 = 100K,
R3, R4 = 330 Ohms,
R5, R6 = 470 Ohms, 2 Watt,
R7, R8 = 22 Ohms, 5 Watt
R7, R8 = 22 Ohms, 5 Watt
C1, C2 = 0.22 uF, Ceramic Disc,
D1, D2 = 1N5402 or 1N5408
D1, D2 = 1N5402 or 1N5408
T1, T2 = 8050,
T3, T4 = TIP127,
T5, T6 = 2N3055 (TO-220)
T5, T6 = 2N3055 (TO-220)
General purpose PCB = cut into the desired size, approximately 5 by 4 inches should suffice.
Battery: 12 volts, Current not less than 10 AH.
Transformer = 9 – 0 – 9 volts, 5 Amps, Output winding may be 220 V or 120 volts as per your country specifications
Sundries: Metallic box, fuse holder, connecting cords, sockets etc
Testing and Setting Up the Circuit
After you wrap up the above clarified inverter circuit, you may do the testing of the unit in the accompanying way:
At first don't join the transformer or battery to the circuit.
Utilizing a little DC power supply power the circuit.
On the off chance that everything is done rightly, the circuit ought to begin wavering at the evaluated recurrence of 50 Hz.
You can check this by associating the pushes of a recurrence meter over T3's or T4's gatherer and the ground. The positive of the nudge ought to go to the authority of the transistor.
In the event that you don't claim a recurrence meter, it doesn't mind, you do a harsh checking by uniting an earphone stick over the above clarified terminals of the circuit. On the off chance that you hear a noisy murmuring sound, will demonstrate that your circuit is creating the obliged recurrence yield.
Presently its opportunity to incorporate the battery and the transformer to the above circuit.
Unite everything as indicated in the figure.
Interface a 40 watt brilliant light at the yield of the transformer. Also, switch ON the battery to the circuit.
The globule will quickly go ahead brilliantly… ..your custom made 50 watt inverrer is prepared and may be utilized as wanted by for powering numerous little apparatuses at whatever point neede
not checked !
