okay i will try it .. so i will place a diode the +ve on the 12v and the -ve which will feed the CHIP ... is it the same for mosfet version or something need to be replaced or dropped

ALERTLINKS : Thank you ... i never thought about that .. but if so then this inverter has a very very poor efficiency because i'm using 12v/50AH battery... i think even if i could make it work it won't handle a good load..... now i know i must use the ferrite ( SMPS ) inverter it's beeter...
I plan To Pure sinewave .. but when i started with that circuit i just wanted to try .. even though it's failed ... then i moved to SMPS inverter but this time i wanted to start with the Pure SW dEsign
okay here is the link ... i have built the mosfet version ..i think it's a famous circuit

i have tried the iron core inverter ... got the 220v output but when i try to connect a load it keeps restarting ... dont know why and searched the net didn't find any solution..except that sure no problem
Dear nikhilmahasvar
Thanks alot .. i got the microchip App notes ..although alittle advanced for me but it provided me a lot of usefull information ...... i just need a basic design to start with.
Please if you or any other can provide me that i'll be very thankfull
Thank you BawA .... you are right i totaly forgot that ... the output voltage is 220vAC/50Hz and i dont actually know the carrieer and fundamental frequency
Hello My Friends
I'm Working in P.SW inverter ..i've made the DC-DC Stage and Tested it .. my only problem is with the H-Bridge Stage .. i read about the SPWM and have the table ... but dont have a complete schematic for the Microcontroller PIC driving the H-bridge and sure don't have the Hex...
KG300 You are amazing man Cool one fully Detailed and Files.... For the transformer if the turns are available it's better if not i can calculate it i just will wind my first smps transformer
by the way if i have an ETD39 core how many cores do i need to use it instead of the E55 and what is...
chuckey : Thanks for your response and i got what You said .. and for that i will test every transformer individually to make sure it's the same as others .

Mithun_K_Das:
thanks alot but i just didn't get how to connect them or i think u mean other topology than Push-Pull...
hi all
i'm working on a 12vdc 220vac power inverter and just want to know how to parallel more than one ferrite transformer to get more power at the DC-DC stage which is 12vdc to 340vdc
