Hi Sven,

The current is continuous according to the mathematics and to my experience. That's principle used to design flyback pulses and they reach the voltage designed for by using the formulas describing that phenomena.

Circuit simulators also use the formulas to bring up the solution which has to fit the practical experiment. Of course this involves making the correct models of the components including their different parasitic (not intended) parameters. Else a circuit simulator is of no practical use.

 Hello Ole,
 
 are you sure the current continues to flow primarily through the inductor, he could still do extra work after the inductor.
 
 I think there is something else. I would like to see the one who makes the inductor cool and freeze at work.
 I have already seen pictures of it. But that would be the thermal path from heat to electrical energy.
 Maybe just a dream.

   Hi Sven,
 
 "A flyback converter uses only the stored energy in the magnetic field, the energy used to build up the magnetic field disappears as a loss. Maybe I think that's too easy."
 First energy is stored in the inductor (input cycle) and then it is transferred to the output load (output cycle). The load then dissipates or converts the energy into another form. As long as a current flows it has movement and a magnetic field surrounding it. Decreasing the current decreases the magnetic field of the current. How fast the current is changed determines the voltage that is induced. Or how fast the voltage is changed determines the current that it drives. This is if the inductor has only pure inductance. A real inductor also has resistance and capacitance which also affects the result.

 Ole

   Hello Ole,
 
 I try again with simple words to give it back.
 I think the magnetic energy adds to the added energy. Practically, we only use one kind of energy at a time.

 When I read through the relevant Pdfs by Hector or Dan Combine, it sounds like a dream of the future.
 
 I will try to tune in the 1200W spotlights today and see if this happens at power factor 0.
 I can measure the current across the shunt and see the shift. If that succeeds at power factor 0 and the lights are on, there is usable energy in it.
