ENERGY AMPLIFICATION

[gyulasun]

This sentence in the link I posted above intrigues me, and I wonder if it holds a key:http://hyperphysics.phy-astr.gsu.edu/hbase/solids/zener.html
If the above is true, then it seems to me we're not just looking at voltage increase but a "very large change in current." Could this be an overlooked key to energy amplification in Tito's setup? I'm not sure, but thought I'd throw it out there.

Hi Bob,

I am afraid the highlighted sentence (small voltage change at the Zener voltage can cause very large current change) refers to the vertical distance shown in your link's Figure from the 1 mA point down to the I_Zmax point i.e. it does not mean an actual energy gain but a means to influence (to control) current flow through the Z diode between a min and a max current value at the expense of the voltage source (LC tank and then the C capacitor) initiating the current flow.

Putting this otherwise: the sentence you highlighted refers to a "variable resistor" behavior what you can control by a small voltage change around the Zener voltage, you could consider it as a voltage-level-selective ON/OFF switch that connects two points in a circuit at or beyond a determined voltage level, under that Z voltage it is OFF. When it is ON, the max current that can flow is determined by the impedances and the loads of LC circuits in Cadman schematic, the Zener is not known to add extra energy...

Hi Cadman,

What you describe makes sense but how would you solve energy extraction from the third or fourth etc LC tank or stage you kick from the previous tank or stage?  Because the loads transform into each tank circuit as a "loss resistance", effectively reducing the oscillating energy swing in that tank, right?  IT is okay that you start from a relatively low level and gradually increase it through the stages but common sense has it: the load (or loads) limit you in the end, no?  I may be wrong here of course.

EDIT: if you could draw a schematic on a possible circuit (you envisioned in your above post) with a load connected, that would be great.      (For switches, just use switch symbols,)

Thanks for the clarification Gyula. Good to have you smart guys around.

Zener diode debate:
Tito always talked about the zener as a safety device to prevent runaway.
In this regard it has the same effect as a spark gap placed in parallel in a critical part of the circuit.
When runaway starts, the spark gap will fire - thus limiting the current in the circuit.
This is what Kapanadze did in the aquarium 2 device.
My understanding is that you can use a zener for exactly the same purpose.
If you use a fuse instead , it will stop runaway, but will also kill the circuit.


Tito: Am I right?

@Gyula
You seem to know alot about circuits.
If you dont mind my asking what looks promising to you.

I have alot of idea's just cant seem to find the time and so many directions to choose from.
