Simple question, just for fun: A diode bridge converts AC to pulsed DC (without a filter capacitor). If we have pulsed DC then how should a circuit look like which is able to convert this pulsed DC back to AC (without the means of an inverter)?

A diode bridge folds up the lower half wave so the negative wave becomes a positive one. Now what's the counterpart of this? The task would be to fold down every other half wave of a pulsed DC so it becomes AC again.

Hmmm ...

Substitute transistors for the diodes in the bridge rectifier and drive them with an oscillator.  The oscillator can be synchronized to the zero-crossings of the input waveform, but it does not have to be.

Why not switched diodes like SCR's (silicon-controlled rectifiers, thyristors)? Like the four ones seen on the four heat sinks hidden under the Stepanov cardboard box?

But I still can't see how this could give additional energy by placing something special between the rectifier and the un-rectifier part.

Hmmm ...

But if in the above mentioned video the label »Inversor« is an ordinary inverter then this inverter would have to stand the full load of the output current. I don't think so.

SCR's can be used too, but they have a higher voltage drop between the anode and cathode and suffer from high conduction losses (waste of energy).  Also, SCRs cannot be turned-off when current flows through them, which leads to switching errors (especially when a non-resistive load feeds the electric current back into the power supply). 

For these reasons SCRs have been obsoleted by transistors  (predominantly by IGBTs), that can be turned-off at will and much faster, as well as with less conduction losses.

  If we have a tank ringing up and we tap the voltage at the threshold level of an avalanche diode couldn't we create dc impulses to be transformed into even higher voltages?  Doesn't faraday tell us that the output of a transformer depends on the rate at which the magnetic field changes about a conductor?  If we dc pulse a transformer primary the output no longer depends on ampere turns ratio's.  Wasn't this what Tesla was doing?  He would create a resonant tank using the generator coils as the I and add capacitance to the generator/primary tank unless the capacity wasn't already matched by the transmission line capacitance.  For an avalanche diode he used a spark gap.  This would transfer power from the grid to his transformer primary in the form of high voltage impulses. This pulse would only be produced when the power supply tank voltage reached the breakdown voltage of the gap.  He also used chokes in series with his local capacitance.  This would insure that while the gap was conducting no current flowed from the generator/primary oscillator.  The chokes would allow stable operation of the generator/primary oscillations.  The generator acts as a negative resistance element in a self-resonating oscillator.  After each gap discharge the voltage or what Tesla called pressure would build back up.  The current flow and frequency always stayed stable because only the voltage  of the system was transferred to the Tesla primary.
