the transformer is there just for voltage step up, the main idea is for one way power flow. Normally 50 Hz or any other frequency flow through a transformer both ways but here the power comes from a coil generating as you said SPWM which I understand is just a better way of doing PWM for a fixed...
@KlausST and @FvM yes, pardon, I did get confused , sure a transformer always works both ways the field couples the current between coils. I do know that. I got mistaken in my schematic, what I did wish to make is a schematic where there is a loop with a coil in it that generates HF, but the...
I will make a setup and i'm almost sure how it should work, but I want to check. Sorry for my previous threads being somewhat confusing.
So the idea is this. I have a high frequency generating coil part of a circuit and I need that high frequency to be converted down to mains frequency.
I will...
Ok , pardon for not being full with all the details, I asked this as a more general question. But ok for you and everyone out there let me fill in some gaps.
The coil on the left is a generator coil, the transformer on the right , just assume it has low reactance loaded secondary, the...
So I have a curious question. I have a loop with two capacitors and two inductors. The first standalone inductor is a high frequency generating coil within this loop, the second inductor is a primary of a transformer. The capacitors are coupling capacitors.
my question is this, if the capacitors...
I'm not sure I got what your saying? Are you saying what I already said about increasing voltage across the cap to maximize power transfer at low frequency ?

Huge coil with low reactance? How does that work? huge coils usually have ever larger reactances unless your talking about...
This question is not regards to any specific circuit or design but more of a general inquiry.
Say you have a small capacitance , from somewhere of 500 pF upwards to maybe 500 nF maybe p to 1 uF at best.
Now say I wish to transfer AC current through it , for example , at 50 Hz.
Now for a...
Ok, I guess I will first do the test the way I had planned to see the results and then come back to figure out improvements.
Who said I can't use coax, I can use pretty much anything just that it has to be well shielded.
For high frequency coax would suffice as the skin depth is very small. But...
The flux is parallel to the loop not perpendicular to it, and it's equal on both sides of it. So there can be no induction in the loop as total because field lines are not "looping" through it like they do in a coil wrapped around a transformer core.
I made the loop geometry specifically so that...
So to make matters clearer I'm still coming to terms with the setup myself.
In terms of loop induction that is not a problem, because I have equal flux entering and exiting the loop area on either side of it, therefore induction will not happen. What will happen is the flux that crosses the part...
Imagine there is a wire that passes by an area that has magnetic flux in it. My goal is to shield that part of the wire that cuts flux.
Now I know a magnetic field can't be cancelled but it can be redirected which acts as shielding a certain area from flux.
The flux is 50hz AC magnetic...
what would happen if I took a toroidal core , generated a static toroidal magnetic field in the core and then rotated the core around it's symmetry axis within a larger stationary toroidal winding around the same core?Just for simplicity imagine a toroidal transformer with a rotating core...
I guess one way one could manage this is by having two separate coils on the same inductor , then each coil could have a freewheeling diode but still each coil could only be switched with current in one direction aka DC current for this to work, so in order to get AC like flux, I would need to...
If you can check out my other thread on this very subforums (power electronics) about the axial flux stator and the coils, now if i have my pole pair coils in parallel isn't it the case then that if they get switched ON/OFF one by one adjacent to the next one, since they share the same core, the...
Hey, a while ago I asked here about mosfet switching in a row. I managed to build a chaser based on shift register logic that worked like a "LED chaser"
Now what I want to do is build a simple axial stator , (already have the laminations) where the field actually rotates, so instead of using DC...
