Designing 12V DC-220V AC Power Inverters

AI Thread Summary
Designing 12V DC to 220V AC inverters requires a thorough understanding of circuit design, particularly for different power levels (2000, 3000, 5000, and 10000 watts). The complexity of the design process means that simply searching online may not yield sufficient guidance; consulting an expert or a practical book is recommended. A user is facing challenges with connecting the emitters of 2N3055 transistors in their inverter project and is seeking specific circuit diagrams and solutions. They have attempted to use various components, including a 4047 IC for oscillation and an LM324 for amplification, but are struggling with resistor specifications. Overall, detailed guidance and original schematics are crucial for successful inverter construction.

How to design 12vdc-220vac 2000,3000,5000 and 10000watts. I need a circuit diagrams and detailed discriptions.Thanks Ismail Dari.

First of all is your input AC or DC. Or just ACDC!

The design procedures for the vaious power levels varies quite a bit and is not somehting you can get by just 'googling it' The filter part of the circuit itself involves a lot of things. I suggest you catch hold of some expert or find a book written by an expert (not just theory, but practical also) to help you out.
 
We sure are getting a lot of questions about this lately. Ismail, please read this recent thread where we had a discussion about AC Mains safety:

After reading that, could you please post a bit here about your background in electronics and project construction, and where the inverters will be used? Thanks.
 
I am a new member i am working on one inverter but i am havering problems with connecting the emitters of the 2n3055 transistor to the negative terminal of the battery , can some help out with this please . Thank you

Here is an old inverter circuit used in the 1960's for Capacitor Discharge (CD) ignition circuits, using two 2N3055's. Note that this circuit is for 6-volt batteries.

bob s thank you for your reply but the information you sent me did not hepl me with the solution but all the same i am greatful to you , but i will be happy if you can send me the origanal schemetic diagrame of a 12vdc to 240vac inverter 5oow, i have some other diagrams but they did not work at all, this is the information of what i am working on, i used 4047 ic to create the oscillation , LM324 IC sound chip for amplifing the oscillation wave for the base of the 2n3055 transistors and a ups transformer for amplifing the voltage, but i used 1ohm or 0.047 ohm but on the diagram i was to use o.1 ohm resistor to connect the emitters to the nagative terminal it is because i did not get 0.1 ohm, please helpe to get the origanal information i will be more than greateful.

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
