Hi,

Here is a simple invertor really simple but it will work , you need to follow instructions to up the output V and the Wattage.

Hi,

Here is a charger that will keep a car batt charged to be used with above invertor.

It is garbage.
It needs Tansistors that are not made anymore. Tansistors were replaced by transistors thousands of years ago.

This garbage inverter started at www aaroncake.net and is copied all over the internet.
1) Its timing capacitors are backwards and blow up.
2) Its transistors have avalanche breakdown of their emitter-base junctions that wastes the small output power and helps to blow up the capacitors.
3) The transistors have a base current that is way too small for an inverter.

The power transistor type and transformer have nothing to do with the extremely poor performance.

There are two huge topics in the forum at the original site where many people say it doesn't work and laugh about it.

31 May 2008 10:03 inverter dc to ac 10kw

Can any boday tell me about Overload Protction in inverter circuits to save the battery and the inverter,. Thanks

Added after 1 hours 1 minutes:

I need a practical circuit of a dc 12v to ac220 inverter 2000 watts, control circuit based on PIC microcontroller or Atmel PLD, MOSFETs for power stage and with following protections.
-Ac over and under voltage control ( 180- 250 volts Adjustable)
-Low battery control (Trip)
-Output voltage regulator 240 vac
-Battery charge control(over charge protection)
-Over temprature control
-Over Load protection
-All controls and alarms with visual and audio indications

I will be very gratefull to all for my help.

overload is a measurement of the DC current between the battery and the DC link capacitor (which is at the front-end of the inverter). do not put the current sense between the cap and the inverter.

you are sensing a current that is too high a discharge rate for your battery.

you can also do other things with this current sense such as in-rush current control.

hi all,

I'm very much interested with all the design of inverters.

What sort of program could I open up for these extensions...rar.

I have downloaded all the attachment in here but cannot open the file with extension..... (.rar).

Could you please help me to open up.

thanks

joe

When i right-click on a RAR file then Windows XP asks where to extract it.
There is a program called "Win-RAR" which might be the same.
There is another program called 'Zip-7" or something.

Look in Google for RAR Extract Program and you will see many programs.

My question is how made RF inverter from few uVolts to 3V for small radio power
for example: Very Happy

I joke or maby is posible??????

sorry i have only heard of a z source inverter and know virtually nothing about it.

Mr.Cool

Added after 1 minutes:

zlatkoMM, notice your diodes are fempto amps rated? also, your capacitor is pF. not much energy or current here.

at best you can trickle charge a tiny watch battery, though it would take a few days.

but i like the line of thinking, keep at it!

this inverter surely not for play for 10 KW. This inverter can power up small village for some place with the electricity difficult to reach

19 Oct 2009 10:58 Design of a 10kW Inverter for a fuel cell

hi all just looking at the Transitors you would need alot of them better use the MJ11028G as its 300Watts each also has anyone ever ever physicaly tried the Transformer as explained in the Diagram if they have they would have noticed that with a 12 volt batt on that Transformer that was first posted Primary 12+12 220 secondary they would know that you would get 120 or maybe 140volts if you use a 12 volt battery and have no step up before the Transformer you will need a 6+6 volt or 12volt Center Tapped and 300volts <<< plus the windings on the 240 <<< volt side would need to handle at leased 15amps. so using a normaly Transformer to get many over 1000watts you will need thick copper wire on both sides of the Transformer sure the 12volt side would be alot thicker.
