When outdoors, this small power house can be used for operating small electronic gadgets, soldering iron, table top radios, incandescent lights, fans etc. IP TRACKER AND STATS COUNTER 3000W-AC 5-Year Warranty. In Stock. Professional Testing & Packaging. www.vology.com Let’s learn how to build this homemade 50 watt inverter unit, beginning with a brief description regarding the circuit diagram and its functioning: Circuit Description For More Info Contact Avenue Sound CELL PHONE REMOTE CONTROL THANK YOU FOR JOINING MY SITE Digi-Key Official Site Search Our Huge Selection of Quality Electronic Components Here! www.DigiKe y.com Join this site w ith Google Friend Connect Members (61) More » Comprehensive information including circuit diagram and step-wise tutorials, get it just for $25 or 1250 INR. Working is 100% Guaranteed. contact The circuit may be understood with the following points: Referring to the figure, transistors T1 and T2 along with the other R1, R2, R3 R4, C1 and C2 together form a simple astable multivibrator (AMV) circuit. A multivibrator circuit basically is composed of two symmetrical half stages, here its formed by the left and the right hand side transistor stages which conduct in tandem or in simple words the left and the right stages conduct alternately in a kind of a perpetual “motion”, generating a continuous flip flop action. The above action is responsible of creating the required oscillations for our inverter circuit. The frequency of the oscillation is directly proportional to the values of the capacitors or/and the resistors at the base of each transistor. Lowering the values of the capacitors increases the frequency while increasing the values of the resistors decreases the frequency and vice versa. Here the values are chosen so as to produce a stable frequency of 50 Hz. Readers, who wish to alter the frequency to 60 Hz, may easily do it by just changing the capacitor values appropriately. Transistors T2 and T3 are placed at the two output arms of the AMV circuit. These are high gain; high current Darlington paired transistors, used as the output devices for the present configuration. The frequency from the AMV is fed to the base of T2 and T3 alternately which in turn switch Are you a developer?

Fully Tested, Results Guaranteed. contact CAR INTRUSION CALL ALERT SECURITY You will require the following components for making this 50 watt homemade inverter circuit: R1, R2 = 100K, R3, R4 = 330 Ohms, R5, R6 = 56 Ohms, 2 Watt, C1, C2 = 0.22 uF, Ceramic Disc, D1, D2 = 1N5402 or 1N5408 T1, T2 = 8050, T3, T4 = TIP127, T5, T6 = 8550 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 = 12 – 0 – 12 volts, 5 Amps, Out 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 finish making the above explained inverter circuit, you may do the testing of the unit in the following manner: Initially do not connect the transformer or battery to the circuit. Using a small DC power supply power the circuit. If everything is done rightly, the circuit should start oscillating at the rated frequency of 50 Hz. You can check this by connecting the prods of a frequency meter across T3’s or T4’s collector and the ground. The positive of the prod should go to the collector of the transistor. If you don’t own a frequency meter, never mind, you do a rough checking by connecting a headphone pin across the above explained terminals of the circuit. If you hear a loud humming sound, will prove that your circuit is generating the required frequency output. Now it’s time to integrate the battery and the transformer to the above circuit. Connect everything as shown in the figure. Connect a 40 watt incandescent lamp at the output of the transformer. And switch ON the battery to the circuit. The bulb will immediately come ON brightly…..your homemade 50 watt inverrer is ready and may be used as desired by for powering many small appliances whenever required.
