how to build a simple 2KVA inverter

the diagram is a modify square wave inverter circuit diagram, and if you adjust the frequency by adjusting or turning the frequency resistor (VR 47Ok) the inverter output frequency can be strong enough to power a freezer compressor and some other electronics appliances in a living room. the circuit dont drain battery so fast and its very cheap to design.
the circuit do not have a pulse control so the more load u apply to the output the more the output voltage drop. 
the inverter is not a chopper transformer circuit base inverter it is a solid transformer base inverter, i will take time to arrange how you can wind the transformer. 
to wind an inverter transformer is very easy and may take less than an hour if you are using a home made local winder.

DEAR EMMANUEL
CAN you PLEASE DETAILS TRANSFORMER WINDING WITH TURS AND WIRE GUAGE for 2000 watt and 1000 watt
THANKS
SREEKANTH

i do use a pesinal winding formula that you may not be familiar with, the gage for winding this 24v inverter transformer are gage 18 for the primari and gage 11 for the secondry you have to wind the primary coil first befor the secondry, the number of the turns depent on the size of your limination or transformer but that is not how i do calculat the amount of coil i need when widing, i have a unique formula that always give me what i need, i will creat a vidio of it when ever i have the chance to do so, but for now if u want to make a little experiment you can use an old inverter transformer that is 24v but were you will have a little chalange is finding a transformer that will take 24v in and 220 out because most transformer are been call to work under pulse whidth formula and in that case if you use 24v in with out pulsing the output, the output may give u 350 to 380v output, i think i need to creat another circuit diagram that can work with a pulse width modulation.

helo

can you give a clear kva diagram
including parts list
thanks

sreekanth said...

sorry

very clear 2kva inverter diagram
with parts list
is it sine wave ?

daz said...

can we use only 12 volts for this? what should i do? can you email me the complete parts list ? and your inverter can run an induction motor 1hp? thank you o much...

But I think the primary gage should be thicker if is going to be a step up transformer

Unknown said...

hello sir, i saw your freehand drawing on 2kva inverter.
please is that diagram complete.
can i practice on that. lukutech08@yahoo.co.uk

Pls sir,is dre a dealer dat supply d red made transformer,or do you know of a rewinder that does d inverter transformer rewindin?

hello sir,i studied elect elect from fed.poly auchi,edo state.assignment was given to my class to build an inverter but the one i had then was little bit difficult compare to your circuit.i will like you to brief some of the component you used to produce this circuit because the diagram is not clear to me.i will be glad if only if you can accept me on facebook.big thanks!!!!

Dear Emmanuel are the pins 4,5,6,13 of IC CD4047 not connected with each other? Secondly, the upper set of the MOSFETs have a capacitor 104, how come the lower set have none? Thanks and I interested to try your inverter ckt.

this diagram have know fuse and light emiting diode pls explain more sir

Hi kindly kindly help me with video and a diagram of building a 2.5kva inverter

Unknown said...

I'm young king pls I want to know the type of wire to be use in that 2kva inverter, also how the preset resistor is connected in the circuit.and the value of capacitor in pin 1 and how do I create earthing in circuit.pls I need urgent answer thanks

Goodmorning. Please how can I test the output voltage of the oscillator
