I have several microwave size transformers. And microwave transformers. Also a couple forklift battery charger transformers. One that weighs a few hundred pounds possibly. It's 277/480 and 48v 200-250 amps . I'd love to build a inverter go use it.
Thank you. K = 37 it is a coefficient that can vary depending on the core quality. If good core quality can be obtained K = 36 If the core quality is poor then K = 45

@@AlfredH If it depends upon the core quality am guessing your referring to the saturation. How would 1 know its Flux? The factor being an constant am aware of is the value of 42, which is always the same value.
I wish I knew what was variac's . I seen one at the Salvage yard I could have got for near nothing! I found it years ago before I knew . I would like to build a large pure sine inverter. Atleast 2000-2500 watts. I have a transformer from a huge forklift battery charger. I need 120v 60hz.do you think this would work?? Great video. I was thinking of a push pull transformer.
Alfred I care. I was looking forward to it. I would like a toroid about twice that size or a couple that size.. I don't totally understand the sizing. And winding.I need a push pull of about 3kw. And 24v (21-30v in) and 120/170v out. So a 24-0-24/120-170 . for a inverter. I need 2500-3000 watts at 120v. Using a small inverter as the logic. Or a ups supplying the logic to drive it and a bank of power FETs. Along with the needed support. Caps driver ic. I hope it would keep the safty features. Do you think it be possible. It is very ambitious given my skill and education. I'm self taught. I wish someone was interested enough to help. I want to build it for my off grid home. Thanks for replying. And please look past my rambling. I am very interested in projects like this.
Push and Pull Transformer? I think its best to have them no other way since you'll want to get your peak to peak. I guess it ought to be around 60hz to be fair but ought to find that out on the charger itself??? 120 volt no worries long as your checking its existing windings matches up to the required input voltage along with the amperage you require. BTW the core as an saturation level. Its best not to peak that otherwise you'll be generating heat and might not max out at what you expected.
Excellent video.
Many thanks
Thanx. Having part 2 will be a great pleasure.

Excellent. But bring part 2 as early as possible.
Thank you
I will have video part 2 after 1 hour
12-0-12V. 1500watt data need/1500va
SWG size=?
Reply please
nice work bro..
Thank you
great project sir ...i like ...but I don't understand where the number k = 37 comes from
Thank you.
K = 37 it is a coefficient that can vary depending on the core quality.
If good core quality can be obtained K = 36
If the core quality is poor then K = 45
Alfred how to determine a core that is good and poor ... please part 3 ... wait
thank's
thank you very much
use incandescent lamps that are installed in series against the Transformers for primary roll Tess,Jika masih menyala berarti gulungan harus ditambah
excelente amigo

Good method
Many thanks

How can you get K = 37? Because ihave to stavolt 5000 Watt Iwan use 50 A troid tranpormer whit 50-ct-50.thank you im from Bali Indonesia.
k = 37 is an empirical coefficient. Quality coefficients of transformer core
Nice job but what is k please
muito bom... grato.
Muito obrigado, time de futebol Português acaba de ganhar
hello friend,how you can calculatıng the K (37),you say the another video K=32.35 .....45 i think 500 va=32, 750 va=35....5000 va=45 ?
K = 37 is a changeable coefficient. This factor will vary depending on the core quality

братущак , у меня такой же ЛАТР . Сколько витков нужно на первичку и на вторичку ?

For 2500 watts you will have to use a battery of at least 24v dc
I was going to do part 3, but it looks like nobody cares so I put it down
i will do it later ...

Tại sao K = 37 không phải 42 hay 50 !! ??
Start the video, Scared the hell out of Ben
Y la continuación del vídeo...????
K=45 to 50

You destroyed working regulating transformer for what reason??
If I use it as power amplifier, then I should remove the transformer control
it is like if you destroy a new car because you need one wheel for wheelbarrow !! stupid, don't you think?

230 ~ volt😊
ما فهمت شي
هو حساب عدد الدورات لمكبر المحول الكبير
Alfred يعني بالامكان صنع مكبر صوت قوي
سماعات بييز ام لا
يرجى ذكر المكان الذي لا تفهمه
Alfred المعنى انه كل مكبر صوت يجب ان نقيس قطره وعدد لفات اسلاك النحاس
انتظر المنصب التالي ، والجهد مع مكبر للصوت 30V إلى 40V تبعا. وقوة المحولات. سأفعل المزيد في الفيديو التالي

كشما فتهمت
K=50
Hmmm.. 42?
