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.
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
How did you calculate 14 turns is enough for primary coil? As I can understand, more turns means lower idle current. If you make only 1 turn you will create a short circuit.
@@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.
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"
What should be the secondary voltage of the transformer for 48v battery? As far as I understand 7v is for 12v, 14v is for 24v so is it 28v for 48v system? :)
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.
Is it normal for the inductor to warm up a bit and warm up the transformer with a load of 100W? Can you work without the inductor? Can I make an inductor with a metal toroid? Thank you
