Hi All,

I want to show why I say Series Resonant and not Parallel Resonant, some may not see the difference and there is a big difference:

Series Resonance: Circuit impedance is minimum.
Parallel Resonance: Circuit impedance is maximum.

See: -->LC circuit<--

By Resonating the Circuit we can see a lot of things, Sine wave and not a square wave across the coils, minimum input is needed to start the circuit, other things like Time constants on the coils and so on.

I hope this helps.

All the Best

P.S: In Diagram 3 I have shown that each of the other circuits (Diagram 1 and 2) have this same added capacitance of 1000uF not shown in Diagram 1 and 2.

Hi Everyone,

If one could imagine, the wave would look something like the below picture. The Arrows indicating Peak charge in the Run Caps, 1000uF and 2200uF shown above. The wave would then be falling off, Diodes then conduct...

All the Best

P.S: This wave is Bi Polar and of course we would not get this wave, only half of it!

@All,

I have uploaded 10 more Videos up to -->Akula Vids<--

All the Best

Hi All, Hi EMJunkie

Very good job of analyzing circuits.
Now comes the selection of the ferrite core, ferrite core of the flyback from television and computer monitor, I found that they contained materials are not the same! . .

Dual TL494; now see that's easy
the lower one's an or gate; or 2x pulses
probably set for short pulses


I assume the bottom one is intended to be a higher frequency that the top... it drives the lower inductance also...


The main flow must happen through the pickup coil and 3 diodes... so it's not nessecarilly keeping positive, but forcing the ground side low....


reds are the 'hot sides' of caps, current flows towards them (if current flows away from them, they become hotter)


the 1000 uf near the power input (batter jump) and the 2200uf at the three diodes are in parallel actually... (with a switch between them, but the switch also breaks the 3 diode rectifier)


I guess what drives the current flow at the top is the forward emf of the 13(?) wind coil at top...
which with decreasing current could hopefully make the pickup coil create a flow in the proper direction...


(sorry to scribble all over it)


The bottom left; there's a 'Q2' I think with a 'g5%' .. is that 95?  85?  I'm guessing 9...
