Inverter Circuit 12V DC to 230VAC Sine Wave

[steven]

 :)i have to make the rectifier circuit to run off this inverter so i can use it in my hydrogen/oxygen from water  exsperiment heres a picture of it under construction

The current in the light bulb when it is very bright is only 25W/240V= 0.1A. Since yours is dim then its operating power and current are a lot less.

Maybe you can fix the cause of the hot transistor:
1) Swap the Tesla output transistors.
2) Swap the BD234 driver transistors.
3) Swap the 15 ohm output base drive resistors.
If the other side gets hot then you have found the problem.

 :)thats only a small one sp it may be easyer to work and i can add another  t peace in the middle section  and use that and the left or right section , this will be like bringing the electrodes closer for faster effects

A square wave inverter can provide a reasonable sine wave output with a few modifications. This was a common method long ago before fast switching pwm. This was implemented with scr type square wave inverters but can also be applied to transistor or fet types. Basically the switching current is forced to be resonant producing a sine output. This was good up to several kW's.

The drawback is that the tuning element values are somewhat load dependant. Also voltage regulation is also load dependant. A more complicated sceme can be used which requires a extra tap on each half secondary winding to provide passive feedback to overcome these problems. Performance was typical 2.5% output change for 25% input variation at full load.

Pictures show typical waves to be expected from this inverter. One is from my simulation and other from actual documented test.

  intresting keep up the good work

hai guys this is shiva newly added as ur friend please i want pure sinewave inverter circuit diagram for input 24v dc output 230v ac with pwm based circuit diagram pls send as early as possible.the rating of inverter is 1kv or 2kv simple circuit,

thanking u

It's been awhile since my last visit on this thread and was so disappointed that almost all the attachment is NOT available anymore.

Or it's just me? 


Good day to all..
