Hello!
I have been involved in building inverters for quit a some time, and i have noticed some things about my step-up transformer:
1) the efficiency is less than 60%
2) the current drown at no load is more than 2.5A
3) A 2kva inverter cannot feed a load of 1.2kw (it starts smoking)
I Need you guys to pleas help me with all necessary calculations needed to achieve the turns ratio, number of turns and swg of the coil for a particular power of transformer?
I'm using 220v as inverter output voltage and 60Hz frequency
