Air core transformer question -- help

dakupoto · 2016-01-05T04:36:18+00:00

Could some electronics guru please provide some hints/suggestions to the following ? First, I built a simple DC->AC push-pull inverter with a 12 Volt 7AH sealed lead acid cell battery. The output transformer is a 120 Volt(primary) and 6-0-6 1.5 Amp (max) secondary. This configuration worked fine, and a 60 Watt incandescent lamp connected to the transformer output terminals provided steady light. I replaced the transformer with an air core transformer, obtained by carefully removing the iron core of the transformer used above, The winding is completely intact, tested by measuring the winding resistance of both the primary and secondary, with the transformer not connected. I am fully aware of the reluctance issues but this time the transformer output is just about 0.5 Volts - 1.0 Volts AC. So what is going wrong ? All hints/suggestions are welcome. Thanks in advance for your help.
