This is a schematic of the InverterThis article describes the inverter circuit. The circuit is very simple, very cheap, very effective. It takes 12 VDC and steps it 120 VAC. Wattage depends on your tansistors Q1 and Q2, as well as how "big" a transformer for T1. Inverter can be constructed supply anywhere from 1 to 1000 (1 kilowatt) watts. Q1 and Q2, T1, to determine how much power the inverter can supply. With Q1, Q2 = 2 n3055 and T1 = 15 an inverter can provide about 300 watts. Transformers larger and more powerful transistors can replace T1, Q1 and Q2 for more power. The easiest and cheapest way to get a large T1 is a reinsurance wind old microwave transformer. These transformers are rated about one kilowatt, is perfect. Go to a local TV repair shop and dig through garbage station, until you get the largest you can find a microwave. Larger microwave bigger transformer. Elimination of transformers, careful not to touch the large high-voltage capacitors may still be charged. If you prefer, you can test the transformer, but they are usually okay. Now, remove the old 2000 V secondary, being careful not to damage the host. Leave the main in tact. Now, the wind in the 12 wire, twist a loop (center tap), and wind more than 12 rpm. The day will depend on how much current wire you plan to have the transformer supply. Magnet wire enamel covering even more beautiful. Now secure the winding and tape. That's all there is. Remember to use high current transistors Q1 and Q2. 2n3055 'years in the parts list can only handle 15 amps each. Remember, when operating at high wattages, this circuit draws a lot of current. Do not let your battery die. Since this project produces 120 VAC, you must include a fuse and build the project in one case. You do? Must use tantalum capacitors C1 and C2. Conventional electrolysis chemical will cause overheating and explosion. Yes, 68 Ultrafiltration is the correct value. No replacement. This circuit is very difficult to walk. Differences in transformers, transistors, parts replacement or other things that are not of this page may cause it has no function.
