12V, 1A, 35kHz-50kHz powe supply supply
Newton Brawn, Sun Feb 18 2018, 05:04PMI have watched the Nyle Steiner mag amp article and I became very interested on the Magnetic Amplifies experiment.
I have some experience in the construction of Mag Amp for battery charge, and mag amp dc current supply for the field of synchronous motors, all in 60Hz, BUT no idea how to it will work in the range of 50kHz.
I have intention to repeat Nyle experiment.
For the audio mag amp amplifier the supply:
Shall be square wave supply ?
Shall be sine wave supply ?
Any idea or circuit to a inverter/converter or supply of 12V, 1A, 35kHz simple construction ? The input voltage could be 120Vac or 12Vdc.
Any information will be welcome .
Thanks
Newton

Hi, when you said magnetic amplifier I thought it would be a circuit like this.
each one is powered by there own voltage source, with the inductors coupled. At 100mH with ten to twenty you could get up to 100-1000H.
If K1 is the mutual induance then it is like this.
l1 l2 0.9
L1 l3 0.9
L1 l4 0.9
L1 l5 0.9
L2 l3 0.9
L2 l4 0.9
L2 l5 0.9
L3 l4 0.9
L3 l5 0.9
L4 l5 0.9
The transformers might be like primary and secondary, inductor coupled, adjusting the resistance of one inductor will change one amount of current, I think is like changing one inductance.
hope it helps
