8kW at 120 volts is 66 amps but the secondary wires only look big enough for about 2kW or am I missing something? Also, at 50hz the transformer appears to be 1000VA at the most.
Question why mosfet like irfz44n can’t inverter with 20 volt and the data sheet said 50 Drain to source but anything over 14 volt blow out the mosfet is that mosfet voltage ratio is not in inverting mode but switch mode
I have a question because I want to build one from old microwave parts. Shouldn’t this have a fuse and what kind? Should there be a fuse for the AC side and DC side. I want to build a whole home solar grid. I would like to do this safely.
Very , very good!. But I think that the circuit is good or capable to handle the 8Kw but the transformer is not big enough to handle that much load. One reason for that is that with no load the inverter gives 110v and with a couple of lamps ( maybe 200w load) the voltage drops to 106v. Some form of restriction the circuit has but overall very good and thanks for uploading the video.
Good job I have a question about pin 5 and 9 I want to use 300 volt mosfet to use a 270volt but pin 5 and 9 is my trouble but they have to connected to mosfet drain and am using high voltage so am asking what is best use a buck converter or resistor
I tested the low frequency inverter that I designed but the out put is giving me 106v and when I connect filter capacitor of 5uf the out put dropped to 83v without feedback and when I connect the feedback the out put go up to 85v and the the feedback voltage is 2v minimum. What could be the issue while the out put can't go up to 200v. I used spwm module. Thanks for your reply
I think he means the circuit can not the transformer because the transformer is a 350 watt transformer the more load adding the lower the voltage get because the magnet field is getting weaker he need a bigger transformer with bigger wire to conduct high current making the field much stronger to handle heavy load but am not a fan of heavy transformer core it’s better to use ferrite core and make a two inverter circuit the voltage drop is very little compare to bigger heavy iron core transformer that have a lot of losses in energy
the circuit in pcb like the mosfets are just driver as well as the spwm that generate the pure sine wave. but the real part that generate the high output wattage is the transformer with feedback to stabilize the generated power

@@ab_ab_c My suggestion is get some CHINESE MODULES. It doesn't make for a "NICE BUILD" but they have sorted all (hopefully) the problems out leaving the POWER STAGE for you to build. I like to use COPPER BUSSES not the PCB. These have also a small heat removal advantage and importantly low stray impedances (Which can result in parasitics) that can cause problems in these ckts. 8KW at 125V 60Hz is not a problem HOWEVER What and HOW LONG DO you need it to handle OVERLOADS when eg. A motor starts up. At 8KW you'd need to get probably a custom transformer which you can always UNDER RUN (Reduced power ) as you add more current capacity to the power handling devices over time/ Remember these are POWER CKTS and if yo can WELD STEEL of an outlet think of what this could do with over ¬6X the power.. It is not pretty when things go catastrophic
No knowledge about the transformer you used . When you test you must use a heater or a motor 4 or 5 KW but you used lamps all of them are less than 500W .
La tarjeta driver esta perfecta... Pero el dimencionado de los cables del transformador a la tarjeta es muy pobre... Y eso hace que pierda potencia (de 110 se baja a 104 voltios) le recomiendo hacer la tarjeta de potencia por separado

There are some concerning things here. The mosfets should be electrically insulated from their heat sinks. When you follow the link back to where it is claimed the circuit diagram is, you find only the pcb pattern and an image of a purported “free energy device” (nonsense). TechBuilder has a better design and tutorial, with better safety practices.

Nice, but you would have won my heart is you displayed waveform on full load.

Nice project.
What if you want 60hz? You ran it at 110v 50hz? It's 60hz no?
Depending on where you live in the world it varies from 50hz to 60hz. That's why European plugs are different than American.
On the EGS002 Board there is a jumper you can short to get 60Hz.
We learned there are sine wave boards available readymade by this video thanks 8000 watt. 10 hp
