# Basic Inverter circuit diagram

The following diagram is the basic design diagram of inverter circuit. The circuit will convert 12V DC to 120V AC. This circuit can handle up to 1000Watts supply depends the T1, T2 and transformer used. Please see the note.

### Components list:

Part | Total Qty. | Description | Substitutions |

C1, C2 | 2 | 68 uf, 25 V Tantalum Capacitor | |

R1, R2 | 2 | 10 Ohm, 5 Watt Resistor | |

R3, R4 | 2 | 180 Ohm, 1 Watt Resistor | |

D1, D2 | 2 | HEP 154 Silicon Diode | |

Q1, Q2 | 2 | 2N3055 NPN Transistor (see “Notes”) | |

T1 | 1 | 24V, Center Tapped Transformer (see “Notes”) | |

MISC | 1 | Wire, Case, Receptical (For Output) |

### Notes:

1. Q1 and Q2, as well as T1, determine how much wattage the inverter can supply. With Q1,Q2=2N3055 and T1= 15 A, the inverter can supply about 300 watts. Larger transformers and more powerful transistors can be substituted for T1, Q1 and Q2 for more power.

2. The easiest and least expensive way to get a large T1 is to re-wind an old microwave transformer. These transformers are rated at about 1KW and are perfect. Go to a local TV repair shop and dig through the dumpster until you get the largest microwave you can find. The bigger the microwave the bigger transformer. Remove the transformer, being careful not to touch the large high voltage capacitor that might still be charged. If you want, you can test the transformer, but they are usually still good. Now, remove the old 2000 V secondary, being careful not to damage the primary. Leave the primary in tact. Now, wind on 12 turns of wire, twist a loop (center tap), and wind on 12 more turns. The guage of the wire will depend on how much current you plan to have the transformer supply. Enamel covered magnet wire works great for this. Now secure the windings with tape. Thats all there is to it. Remember to use high current transistors for Q1 and Q2. The 2N3055′s in the parts list can only handle 15 amps each.

3. Remember, when operating at high wattages, this circuit draws huge amounts of current. Don’t let your battery go dead.

4. Since this project produces 120 VAC, you must include a fuse and build the project in a case.

5. Youmustuse tantalum capacitors for C1 and C2. Regular electrolytics will overheat and explode. And yes, 68uF is the correct value. There are no substitutions.

6. This circuit can be tricky to get going. Differences in transformers, transistors, parts substitutions or anything else not on this page may cause it to not function.
