Hi im still leaning about this stuff. Should the turn ratio not be as follows? 220/14=15.7 so should it not be 16 turns per volt? Primary =224 turns and secondary = 3520? Sorry just learning.
This is nice!But I want to ask, what if you increased the number of turns of both the primary and secondary windings in the same ratio?For instance, instead of the '220 turns :14turns', you decided to make use of "440turns : 28turns"
When you finished winding your transformer you should test& show the output voltage like the one you showed in, 1000w. Secondly can I know why don't you use the same original wire insulation instead your using pVC sleeve what is the reason please let me know.
From your calculations I don't understand how you get the secondary current to be 160A and the wire size to be 16mm^2 kindly explain to me your secondary voltage is 14v since the because the 24v is divided into 2 to give 12v-14v

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.

@@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.
Where did you get your transformer iron? If I understand correctly, judging by the dimensions, this transformer was used in an uninterruptible power supply before rewinding, right?

Hi; Is the transformer operated with a full bridge inverter? because on the secondary side the center tap of the coil is missing. many greetings from Germany AND MUCH SUCCESS.
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.
