Akula eternal lantern 4

You could, but that would be entirely unnecessary overkill.  If you generate DC output to the heaters then ordinary EMI filters can easily attenuate the high frequency noise.

Yes, I understand. The negative side is the need of very costly high power high frequency diodes and much more safety precautions I guess in case of heater current  leakage to ground (though heater stainless steel container will be grounded). In fact only the costs of diodes is the main reason and additional circuits to charge big 400VDC capacitor and keep it safe from overvoltage. The output stage of inverter will be 8 separate coils each giving at least 1kW. If I generate rectified DC from AC  will it be enough to supress inductive impedance of such heater elements , without going to filter it with capacitor ?.


MarkE, I'm very greatful that you are here and helping me, thank You!

Well, I think under the circumstances, the safest route for you is to use a traditional heater controller.  You can purchase one or more 20A solidstate relays and control them all from a relatively inexpensive controller off the shelf or that you can design and build.  That will spare you any energy storage components save for the small power supply needed to run the controller.

Works the akula 0083 30 watt ?

I have built  this but the coil L2 draws too much current 3 amperes
And the akula don,t work

Please can some help me

Akula's devices have been reproduced right down to the waveforms.  Non of the replications have yielded free energy.

okay so the akula 30 watt not working  it is fake ?
