Remember to use high current transistors for Q1 and Q2. Enamel covered magnet wire works great for this. The guage of the wire will depend on how much current you plan to have the transformer supply. Now, wind on 12 turns of wire, twist a loop (center tap), and wind on 12 more turns. Now, remove the old 2000 V secondary, being careful not to damage the primary. If you want, you can test the transformer, but they are usually still good. Remove the transformer, being careful not to touch the large high voltage capacitor that might still be charged. The bigger the microwave the bigger transformer.

Go to a local TV repair shop and dig through the dumpster until you get the largest microwave you can find. These transformers are rated at about 1KW and are perfect. The easiest and least expensive way to get a large T1 is to re-wind an old microwave transformer.Larger transformers and more powerful transistors can be substituted for T1, Q1 and Q2 for more power. With Q1,Q2=2N3055 and T1= 15 A, the inverter can supply about 300 watts. Q1 and Q2, as well as T1, determine how much wattage the inverter can supply.It will answer all your questions and provide links to many other (and better) inverter circuits.Ģ4V, Center Tapped Transformer (see "Notes") Important: If you have any questions or problems with the circuit, see the forum topic linked to in the Notes section.
The inverter can be constructed to supply anywhere from 1 to 1000 (1 KW) watts.
The wattage depends on which tansistors you use for Q1 and Q2, as well as how "big" a transformer you use for T1.
It takes 12 VDC and steps it up to 120 VAC. Have you ever wanted to run a TV, stereo or other appliance while on the road or camping? Well, this inverter should solve that problem.
