What is it that went through the diode to the converter output Capacitor then?

Hi Bistander,
Thanks for the diagram, The current flow in red that was labeled when the inductor is switched on, is the current flow I was talking about indeed. I was thinking that it could be stored in a pair of ultracaps and reused.

Until I work out the feedback technique for some chips Ive got and can build the circuit, its only a thought experiment for now. There is probably a complicated reason why it wont work. Some one knowledgeable like yourself could make a believer out of me and save me the wasted time.

What I believe for the most part. that goes thru the diode to the load, is a copy of the input power. And the input power is sunk to ground, give or take, depending on the topology and their variations.

Hello Lotec,

The part above which I bold out plus the underlined one (as the meaning of) encloses the whole concept, and yes, exactly hit it on the nail head!!

And so I will add...that it depends of how many "copies" per fraction of time are sent to output...based on also, their magnitude...

These "copies" are hefty transients which get to the point of being above Input Voltage...plus also adding V In minus Diode Voltage losses.

Where I see a pure wasted energy...is in a lost Magnetic Field which is not inducing another coil...also making "more hefty copies" and delivering them to output...

Hi Ufopolitics,
Thanks for the input. You see it too, along with a few others. I wont pretend to be the first. People on this forum have dropped these kind of hints for years on and off, but I haven't seen so much to pursue the idea.

I was cheeky calling it a copy, most people probably call them counter or back EMFs. As Boguslaw pointed out "copies minus losses".

I think you're right when you say the magnetic field and its counter MMFs could be utilized more fully. If I understood you rightly you mean copies of copies. Thats a skillful endeavor, from what Ive seen impedance is the biggest enemy, it can choke the circuit out and cripple the throughput. Once impedance rears its head it can recurse back through the generations to the original pulse. (Not saying it cant be done). My belief is that if x amount of energy can be cohered from the original and first gen copies, that there could be options for staging ,stacking or compounding the results.

You are welcome, Lotec,

These "hints" are based on real experimenting that dates back to years of research, my friend...

I was cheeky calling it a copy, most people probably call them counter or back EMFs. As Boguslaw pointed out "copies minus losses".

The Inductor, Reactor or simply Coil-Core assy...when field collapses (FET switch Off) sends a "Hefty Transient Spike" which goes through Diode to Output Cap-Load.

And actually this Discharge at Off Stage is what basically feeds the Load minus Diode losses from Out Cap.

Now at Charge Time (see my Diagram below):

We can clearly notice above that V In is NOT going through Diode, so, what feeds during this "Inductor Charging Stage" to the Output Cap and therefore Load... is the remnant charge from previous discharge stage...from exactly those "Transient Copies".

Ufo,

When the switch is open:

V(out) = V(in) + V(L) - V(D)

That is the mechanism providing the boost (ie. making V(out) higher than V(in). Of course other design considerations must be in line like inductance, capacitance, frequency and duty cycle.

From my point of view...V(In) affecting/feeding Inductor (L) never makes it to Output at charge stage, on this particular circuit design...but whatever remnant charges from discharge stage are at out cap. Concluding that V(In) is NOT Fully present at Output.

And the way you see V(In)[Lotec] (sunk to ground) is as Bistander told you before...if it were not attached to ground (negative) it would not close the circuit...therefore, inductor wouldn't get charged.

It is NOT about CEMF nor Back EMF...it is plainly about EMF SPATIAL Induction on a Secondary Coil, using same core from same inductor on circuit above...using same operating mode...On and Off.

No one pays attention to a Huge Magnetic Field generated every time Inductor is ON (Charged), as when this Field collapses, it could be arranged to be Induced reversely by a Secondary Reactive Field Circuit (Looped as an LC Tank)...which will also Induce on Secondary(ies)(your call them "copies of copies") to Output...

But then again...if we have a switched device which could do 99% Efficiency based on "A Copy Repetitions through Time fast frequencies"...with this additional Energy manipulation it will easily surpass the Unity...and become OU...A Taboo according to many here...

Hello Bistander,

If you take another look at circuit diagram, basically at Discharge Stage (switch open)...the Positive Voltage at Input [V (In)] is not charging Inductor here, but just passing through Inductor wires (and of course adding to Inductor Discharge V) as to contribute charging Output Cap which is grounded.

Meaning, yes correct above, and I agree...but, realize that V(in) is CONSTANT, as is V(D)...what is NOT Constant, but completely dependent upon Driving Frequency through Time is V(L)..

Concluding that V(L) is the only component which could either increase output to max (boost)...or sink it down below (buck) given the driving frequency.
