Winding the transformer is the main key,I wound many transformers which none worked properly because leakage inductance or parasitic capacitances make HV spikes and oscillations on the drains of mosfets,I disassembled an inverter to see the transformer winding method, it was copper strip(full length of bobin)2+2,after that entire secondary of litz,and another primary copper strip 2+2 in paralel with the first one,it worked flawlessly in that inverter without snubbers,rectification was sonchronised with GDT with IGBT

Thanks for information 👍

[@cipry1010]

That hammering to the windings does distroy the insulation and risk of arcing it is not a good practice,if you can’t bend the wire square maybe consider using and ETD core

[@Electronic_For_You]

You are right, maybe it's better to use copper stripes instead of wires , because wires are harder to bend 👍

Hi, what is the transformer rating and frequency? And how that frequency converted to 50/60Hz? Hope you answer in a little detail. Thank you.

Good day Sir, on a H Bridge of power inverter, i have always mosfet 1 (high side) and mosfet 2 (low side) that burn while 4 and 3 stay ok. Please note that they burn ONLY WHEN I TURN IT OFF, when ON, all is good. When i use only 3 mosfets, none burns (1,2,3 or 2,3,4). I checked on the scope, signals are identical and voltage between gate and source are the same for low and high side. I am running out of mosfets and i would like to fix that inverter, any idea where to look at ? Thanks.

[@Electronic_For_You]

Where you got voltage supply for the H-Bridge? Is it Isolate?

[@hichamtassi1753]

@@Electronic_For_You the voltage Comes from 3 capacitors in parallel of 150uF 450v for approx 289vdc. I checked also the deadtime, it is present everywhere...

[@Electronic_For_You]

I mean for driving the IGBTS! Is it from 12V input? Or isolated?

[@hichamtassi1753]

@@Electronic_For_You Hello Sir; the issue is fixed, i found a broken ground trace going to emitter of some smd transistors. The gates were not properly discharged. THANK YOU very much for your help which guided me to repair !

[@Electronic_For_You]

Good to hear that your problem is solved ! You are welcome!

Cna you give me links for this bobin and core ? ❤

[@Electronic_For_You]

Hi, Its in video description

[@MrBoi96969]

Have you ordered this core from AliExpress in INDIA??❤

[@Electronic_For_You]

Hello, You can see by clicking the link in description if it's Available to buy it from your Country!

[@hp2073]

1000w means at least 83A (12V input) from the primary of the transformer, are you sure about your calculations?

[@Electronic_For_You]

1000Watts peak, 750W Continuous 12V@60Amps

[@hp2073]

@@Electronic_For_You My calculation says for 65A or 750w you need 14×1mm wire which is impossible on a single transformer. I dont want to say you are wrong but if you can, please guide me.

[@Electronic_For_You]

This is a pulse transformer rated for 1KW in some cases this thing can output 3kW and this type of transformer works on high frequency, 30-60khz so we Don't have to use thick wires, i think your calculation is wrong, this is not a 50/60hz mains transformer!

[@hp2073]

@@Electronic_For_You how 3×1mm wires can tolerate 60A?

[@Electronic_For_You]

Not 3 Its 4×1mm and each wire will handle 15amps so total 60amps

[@sagorrana2051]

I think, 12v input 2 turn is enough

[@Electronic_For_You]

3 turns used to decrease Idle current consumption 👍

[@eboy536]

Ur thinking! What's about formula

[@cipry1010]

It depend on the core Ae

Kuch log ise 3kw tak power lete h uske liye kya modificatiin hoge sir guide me

[@Electronic_For_You]

You have to wind for 48V

Can you leave the schematic also?

There is also a diy version

12v to 220v inverter 1kW circuit diagram please sir.

I already did it in one of the previous videos, you can watch 👍

[@electronica_h5]

Tu estas pelando el alambre dándole con la pinza de hierro

[@Electronic_For_You]

its ok, double insulated wire 👍

[@deanbell5164]

1KW @ 12V = 83.3A you are dreaming!!!

[@Electronic_For_You]

It is also possible to use 24V 👍
