Power inverter is commonly known as UPS. UPS stands for uninterruptible power supply which is the modified form of inverter. Due to the lack of electricity the importance of inverter increases day by day. The substitute of load shedding is generator or UPS.<\/p>\n<p><strong>Few advantages and disadvantages of generator are as follows.<\/strong><\/p>\n<p>Its first advantage is, it can run many electronic devices and it can supply electricity for the long duration of load shedding. The disadvantages are noise pollution, usage of fossil fuel cost it too high. The alternate of generator is UPS, it has also some advantages and disadvantages.<\/p>\n<p>The supply of electricity goes uninterrupted, it do not require much effort. Its backup depends on battery, as many amperes of the battery it has, that much it backup it would provide.<\/p>\n<p>Its disadvantages are, recharging takes a lot of time and in the long duration of load shedding battery cannot b recharged so that it stops working. By putting excessive load the duration of backup reduces. Its performance is about 60% to 90%.<\/p>\n<blockquote><p>Today I will teach u how to make 500 watt inverter which anybody who has fundamental knowledge of electronics can make it.<\/p><\/blockquote>\n<p>Following things are required for its construction.<\/p>\n<h3><strong>Components:<\/strong><\/h3>\n<ul>\n<li><strong>Transformer 40 amps (500 W), 220 V, 12X12 V<\/strong><\/li>\n<li><strong>Transistor (10) 1047<\/strong><\/li>\n<li><strong>Resistor (1) 500 ohms<\/strong><\/li>\n<li><strong>Battery 40 Ampere<\/strong><\/li>\n<li><strong>Multi meter<\/strong><\/li>\n<li><strong>Capacitor 250 V, 0.5 uf<\/strong><\/li>\n<li><strong>Wires, soldering wires,<\/strong><\/li>\n<li><strong>Soldering iron<\/strong><\/li>\n<\/ul>\n<h3><strong>Method:<\/strong><\/h3>\n<p>First of all, you have to make some changes in the transformer. If you are using a 500 V transformer then take 18 to 22 gauge copper wire and on the one side of the transformer\u2019s core make five turns and put a point on it, and turn this point, and again turn the wire five times on the same direction.<\/p>\n<p>In this way, you get three terminals. If you connect the transformer to a 220 V power supply then it gives 1.5 V on both terminals.<\/p>\n<h3>How to fine Base, Emitter and Collector:<\/h3>\n<blockquote><p>Now put transistor D1047 on the palm of your hand and turn it such a way that number appears your way. Now you will see three points. The point on your left side is known as (B) Base, the middle one is a collector(C) and the right one is (E) emitter.

Connect the base of all five transistors altogether and then join the points of collector together.<\/p>\n<p>In the same way, arrange the other five transistors individually and connect the collector(C) of both sides of transistors with the outer terminal of the secondary coil, after that connect both outer terminals of the third coil with the base of both heat sinks of the transistor. then connect the (E) emitter of both sides by wires n then connect the 500-ohm resistor on the emitter and resistor on either side. Now connect the middle terminal of the primary coil by one to two ft long wire and clip (crocodile) it and attach this terminal always by the positive terminal, and with the negative terminal of battery connect the both (E) emitter of the transistor.<\/p>\n<p>After that the central point of the third coil and a wire attach it with emitter to connect using a heavy ampere switch between both terminals of the Inverter primary coil to apply a capacitor which will prevent the current from the sparking. inverter will switch on as soon as starting to work.<\/p>\n<blockquote><p><span style=\"color: #ff0000;\">Discussions about Pakistan Science Club's Power Inverters 12 VDC to 220 VAC UPS, you can find problems, troubleshooting and construction help Please visit <a title=\" Power Inverters (UPS)12 VDC to 220\" href=\"https:\/\/forum.paksc.org\/Forum-Homemade-UPS-inverter\" data-wpel-link=\"internal\">Power Inverters (UPS)12 VDC to 220\"<\/a><\/span><\/p>\n<h3>Working:<\/h3>\n<\/blockquote>\n<p>With both the terminals of battery connect the positive and negative wires to its terminals positive to positive and negative to negative and then open the switch, slightly vibration starts in the inverter as switch is open.
