Anyway, if you put a CSR in series with the inductor in such converter and use it to measure the current flowing in that inductor, then you will observe the same all positive triangular waveform when a resistive load is connected. ------------------------ Dally, Shark & Ruslan workbench IMG_20211026_173915_351.jpg (72.15 kB, 1561x1658 - viewed 1536 times.)

Group: Guest	Verpies: Yes, but only showing what happens in normal closed circuits, not in open systems, which are tapping into the underlying Aether source, which THEY don't believe exists. Simply because they can't prove or disprove it, yet. Like Dark Energy, etc... Or like ghosts, can't prove them, either. So, they don't exist, for science. Right? Those are some of the self imposed current limitation that science has to deal with, which are still the case. If we don't consider the non physical causes of the physical effects that we see, we are still blind to the reality of the cosmos. NickZ

Even in boost converter am using as an example, current still flow in one direction inspite of the resistance. That should not be a yardstick. If you look at my picture, you would see that when the positive pulse was at MOSFET gate current passed. The question is would that had been all. That was just resultant current. You see, there is a misconception here that we have to get clear. I never said current will not flow. Of course current will flow but, not without resistance.

Group: Guest	Quote from: Maxolous on 2021-10-26, 17:48:30 Remember , when inductor rise in current reaches it's stead state a time "t" only the resistance of inductor will be left, hence the reactances is cancelled . Therefore, for the above cct. It becomes almost a short cct. which strongly opposes current flow. The voltage that you get after diode will be much greater than that applied. Max: How about the actual power factor? Will it also be greater. Or, Is it just the voltage that will be higher, but, at the expense of the current? Boost converters... will this discussion lead to how to obtain OU, and such. All closed system have resistance, and is why there is no free lunch there. NickZ

Yes, if you orient the diode in such a way that the current flows from the voltage source to the load even when the transistor is opened. If the diode is flipped around, then current will flow through the load only after the switch has been closed for a while and after it opens. But, you are switching subjects. The energy storage in an inductor is not the point of our discussion - the direction of current flowing through that inductor - is. If you want my analysis of inductive energy storage and recovery then read this.

That was just resultant current. You see, there is a misconception here that we have to get clear. I never said current will not flow. Of course current will flow but, not without resistance. The mere constant current flow through the inductor is not the issue. I have already analyzed the "steady state" at the "V/R limit" here. The direction of this flow is the issue when the transistor switches. Quote from: Maxolous on 2021-10-26, 18:02:41 If you look at my picture, you would see that when the positive pulse was at MOSFET gate current passed. Do you mean "has passed"? Isn't that equivalent to the MOSFET being open ? If "yes" then, I agree that in the boost-converter circuit, the current will flow through the inductor and the load when the MOSFET is open. ...but the direction of current through the inductor DOES NOT REVERSE when the MOSFET switches (even if the EMF across it does). Insert a CSR in series with the inductor and see for yourself. Anyway, the boost converter is not the most illustrative example because the inductor's current never reaches zero. A more educational circuit to analyze is the one with the diode flipped around, like this: If you connect the scope across the CSR, then you will also see an all positive waveform ...ergo - no current reversal.

Group: Professor Hero Member Posts: 3498	Quote from: NickZ on 2021-10-26, 18:04:18 How about the actual power factor? Power factor relates to AC voltage sources and reactive loads, not to DC-DC converters. Thus your question is irrelevant to this discussion. Quote from: NickZ on 2021-10-26, 18:04:18 Or, Is it just the voltage that will be higher, but, at the expense of the current? Yes - voltage in DC-DC converters is converted at the expense of current or vice versa. Quote from: NickZ on 2021-10-26, 18:04:18 Boost converters... will this discussion lead to how to obtain OU, and such. Not directly. It will only lead to a better understanding of conventional LR circuits ...and answer questions like: "What is that diode doing?" Quote from: NickZ on 2021-10-26, 18:04:18 All closed system have resistance, and is why there is no free lunch there. Superconductive inductors exist and they are really devoid of resistance. The current can circulate in them for years. Still, even in the absence of resistance they do not exhibit OU. P.S. I noticed that you deleted your question "What is magnetic flux ? Magnetics 101"

Hero Member Posts: 2735	verpies Quote Connect a scope probe across R1 ( a Current Sensing Resistor [CSR] ) and pulse the Q1 and see for yourself that the direction of current in L1 does not reverse when Q1 opens. Polarity of voltage - yes. Polarity of current - no. I agree and we can also place diode(s) on the output to determine the direction of the current or LED's on low power circuits. Strangely, most people get this wrong if they didn't learn the fundamentals or are not following the scientific method. We basically use the left hand rule for electron flow then follow the magnetic field direction(expansion/contraction). I like to break it down... 1)if we apply an emf to a conductor it produces an increasing electron current in the conductor. 2)the increasing electron current produces an outward expanding magnetic field. 3)the outward expanding magnetic field cuts the same conductor inducing an emf in the opposite direction to the applied emf/current, ie. self-induction. 4)If the applied emf/current is reduced then the magnetic field must start contracting inward. 5)If an outward expanding magnetic field induces an emf which opposes the applied emf/current then an inward contracting magnetic field must induce an emf in the opposite direction which is now the same direction as the applied emf/current. More important is understanding that bulk equations and generalizing things cannot replace a good understanding of what actually happens on the most fundamental level in reality. In reality we are dealing with particles, fields of force and energy as the motion of particle/fields. All this free energy stuff gets much easier if we can learn to think on a deeper level.

Maxolous Max: Just to be clear, so then it's the only the voltage that is raised, but at the expense of the current. Nothing gained, except higher voltage. Why is this important to mention? As it seems pretty basic, and well known. NickZ

Because not knowing the basics is harmful to experimantation. Also, knowing the basics allows one to spot an anomaly. For example if I would see the current in an inductor suddenly reverse its direction, than it would get my attention and I would pursue this anomaly. Without knowing that it is an anomaly - I'd never notice it as anything special. Knowing the basics allows you to know where to aim your gun more precisely and not to shoot phantoms.

This big table and this at the bottom of the page gives us a hint what it is. Yes, there are many things that we don't understand, and possibly never will. We still wrongly call Light, a particle. Such as in a "Particle of Light". Which equates to light being a thing, when it is a non thing, instead. Or, Is it really a "particle", as we know a particle to be, Really? And does it actually move? As in the calculated "speed of light". What is it that is actually "moving". I don't mean to receive a copy and paste article about what is Light. Just saying... What we are dealing with here are not just empty theories. Like the Big Bang, and other current miss information. And we, at least some of us are really working on self running systems. "Abstractions", may not be the best way to describe all these ideas dealing with energy, EMF force fields, magnetics, gravity, vortex field energies, and such. However, I know what you mean, and do agree with it, most of the time. However, it's those field energies that we need to tap into, as Tesla has suggested. It's hard know where to aim your gun, when you can't see what to aim for. NickZ If I removed the Magnetics 001, post, that was not intentional. Feel free to comment.

Group: Guest	Thanks Verpies, I appreciate that. I will consider what you mentioned, about who is doing the moving. A little funny, like Nelson would say? However, Isn't EVERYTHING moving, can't stand still, even the non things??? Yes, dead heads like me move. Light does not "move", it polarizes at the so called "speed of Light". There is a difference... NZ

Even protons and electrons always spin.

You send it, and it's there, eg instantanious telepathic communications, as Tesla had mentioned. If one throws a piece of wood in a river. Is the wood moving, on it's own power. Or not...?

Sr. Member Posts: 389	Lenz’s law, in electromagnetism, statement that an induced electric current flows in a direction such that the current opposes the change that induced it. This law was deduced in 1834 by the Russian physicist Heinrich Friedrich Emil Lenz (1804–65).

Lenz's law is my favorite subject for conversation. When you use the word "reverse" you are not specifying "reverse" with respect to what ! e.g to past current, to current in another coil, etc... Also, when the word "reverse" is a sign comparison operator, and as such it can only compare quantities of the same type. e.g.: current to current ...or voltage to voltage. Also, your definition of the Lenz law is ambiguous. It should be: "...a reverse current will be induced in the direction that will generate an internal opposing magnetic flux to the external magnetic flux which would otherwise change the total magnetic flux spanned by the inductor". Quote from: Maxolous on 2021-10-26, 22:12:18 In a nutshell, a charging magnetic field always produces current having a direction which opposes what induced it. Not quite. It should be rephrased like this: "...a changing external magnetic flux always induces current in a conducting coil that will generate an internal opposing magnetic flux and that flux will attempt to keep the total flux spanned by the conducting coil, constant". If it does not, e.g. because the coil is open, then the total magnetic flux spanned by the coil will not be maintained constant. Notice, that the induced current has only ONE DIRECT CAUSE. Namely the external magnetic flux (Φ_EXT) which attempts to change the total flux penetrating the coil (Φ_TOT). The induction is not dependent on local magnetic flux densities (B) within the coil (only on its closed loop integral, which is flux). In Mathspeak: Φ_TOT = Φ_EXT + Φ_INT In an ideal shorted inductor coil Φ_TOT always stays constant regardless what the Φ_EXT is attempting to ...do and that implies that Φ_INT = -Φ_EXT ...a perfect and perpetual opposition of the internal flux to the external flux. In a resistivity coil, the opposition is not perpetual and decays with time.
