Make 100A transformer 2000W for Inverter Sine 

congratulation.

Next video: D

Yes, it is a good idea, I will do it

@@PhdHung what is mean by

ok, xuyến dễ quấn mà.

thanks bro

The choke will filter the high frequency voltage before going into the transformer. It reduces the no-load current. I have seen several Chinese inverter boards that use it before. So I tried, it worked fine. aliexpress.com/item/32909770919.html

@@PhdHung Thank you for explaining this to me Homemade 102. Good day too.

It reduces the no-load current

@@PhdHung Chokes is not to reduce no-load current. Its main purpose is to reduce sudden inrush current when the transformer is switched ON. The inductive reactant of the transformer is the main resource of impedance in a transformer. The inductive reactant is zero when the transformer is OFF. It comes to the picture when a transformer is ON. Hence when we switch ON the transformer, it takes heavy current at starting (like AC Induction Motors). This current dies once the inductive reactant of the transformer comes into the picture ( as a transformer is ON now). To protect the transformer from damage due to heavy starting current, the choke is connected in series of the transformer. The inductance of the choke is selected in such a way that it offers high impedance to heavy current, but the low path to normal current.

@@jameelsheik If the transformer does not have an inductor in series, the power stage may be affected ... are the mosfets burned?

thanks

Yes, it works with H-bridge, I built H-bridge and SPWM control circuit. If you want, you can review the videos in my video list.

@@PhdHung DANKE.

@@PhdHung nh n

Thanks

install it directly. EGS002 is ready to work

Ok thanks....

Not enough space. However, if using 440 and 24 turns. No-load current will decrease. Fine, no problem.

@@PhdHung this may make the transformer more efficient.

Why?

Thanks bro

I use H. Bridge with voltage feedback. It requires 7Volt primary coil / 12V battery system. If using 24V battery system. It needs 14V primary to 220V.

No, the coil is very cool, you may not need it, but your transformer must be of good quality

Como permitir que um inversor consiga pôr a funcionar um congelador?

inverters using iron transformers will work for a long time, have a large power, can overload without burning. However, the performance is lower than that of the inverter using a pulse transformer, it is also heavier and more expensive.

ok, wait me

EGS002 requires the voltage of transformer is 7V with 12V battery system, I use 24V battery, so I need to build transformer 14V to 220V.

@@PhdHung my brother honestly I must have watch your videos at least 200 times. May I most humble ask another question? After you do the you do the first sets of turns do you put the wax paper in between each sets of turn until you reach the set turns are you can do turns on top of turns until you reach your set turns? I am doing for 110v @ 146 turns?

It reduces the no-load current.

The wire has a 16mm cross section, according to the datasheet, it can load 160A. but I only use up to 90A. So it is very safe.

@@PhdHung I like and Appreciate your work u r doing very well keep it up. A transformer having bobin size of 2×3 coiled with 10 swg and 19 swg for chagring and inverting how much output it will give kindly guide me

Primary transformer 12 turns ~ 14Volt

If you use 20A transformer, you will have max 20A x 12V = 240W. or 20A x 24V = 480W

@@PhdHung And 20A x 48V = 960W, if you use 48v and 50A you get 2000W half the weight of the transformer, better performance.

Add an inductor, like I did

It filters high frequency signal before entering transformer. It reduces the no-load current.

@@PhdHung Thanks for the reply

ok. Post your request on Facebook. Everyone will calculate for you.

Yes, but you need to increase your wire size. and use battery> 200Ah

reduce the no-load current.

@@PhdHung it reduces the inrush current during switching.

i need transformer core size, i will calculate it for you.

why? Did you calculate anything or are you just talking?

Yes u will have to rewind

That's a good idea, I'll design it

@@PhdHung yes we will wait. Because it is better for future.

probably not. It is a little small

Do you want to use it at 12V or 24V? If you use at 12V, you need a single 7V transformer to 220V. If you use a 24V battery, you need a 14V to 220V transformer. Your 100A transformer is great, but it needs a little fixing on the primary winding.

@@PhdHung i want to use it at 24V... so i have to rewind it both primary and secondary? thanks

No, just edit the primary coil.

@@PhdHung thanks and more power....
