Hi Edaboard community, I have a quick question about rectifiers.
It seems that when you run an AC simulation with a rectifier, the rectifier behaves like if there is nothing.
Below I show what i'm talking about. I simulate an AC source with a 5 ohm resistor (R1) and same resistor (R2) with a...
Hi there,
Does anyone of you know a simple software for electronic circuit schematics. something that do nice shapes for presentation.
I need to draw some RLC models schematics and all the simulation software (Ltspice, eale etc...) doesn't have nice shapes. Usually I draw it directly using Word...
@betwixt
Yes completely agree with your point. However there's still some advantages by using SMD caps, you have a well fixed capacitor and the size is small.
The capacitor is reasonably low ~100pf. I've already thought about using air capacitor+motor but didn't like this solution because it...
Hi I would like to design an automated tuning capacitor controlled by a microcontroller. This tuning capacitor should have a high quality factor and accept high voltage (>500V).
Here I explain why I need it. I design many different LC resonant circuits and each time I have to tune the capacitor...
Hi,
Lets say I want to use any ADC that has at least 16bit-1MSPS (LTC2378-16 for instance or any other). I would like to know what I should use for reading/saving these 1MSPS from an ADC. Should it be an FPGA? a CPLD or a microcontroller can do the job?
In my application I have an event that...
Hi dear friends,
I have some questions about ferri/ferromagnetic materials for boosting Inductors Q factor. This sort of things is out of my knowledge so I don't know how to properly choose the right magnetic material for an application. As far as I understand things, for any magnetic material...
Hi,
I am trying to draw the equivalent model of more than 2 coupled inductors.
For two coupled inductors, the equivalent model is the one below.
For two inductors coupled to a third one, I have found this:
This circuit was found with the formulas from here and by neglecting M23:
**broken...
This should not depend on steady state or not, the phase should stay the same.
However, you are right the problem comes from the time step. If you don't define it, I guess it fix it chose a big value and then you got a divergence after 10k points.
I think here is the problem. When you run an AC...
Hi,
I was working on LTSpice when I encountered a problem between AC and transient simulation. I was simulating the simple RLC circuit below:
I was searching the frequency when the imaginary part of impedance is equal to zero im(Zin)=0.
From AC simulation I get something like 6.497MHz which...
Ah yes I haven't seen that there were some non inductive rated resistors.
There are even some special RF resistors at 40$ :( https://www.digikey.com/product-search/en?keywords=%09TGHLV1K00JE-ND
But here again they don't give any characteristic or frequency range.
To Fvm: Thanks for the...
Hi,
I have designed a DC to AC 1MHz converter and I would like to test it with different loads. I am expecting to use some dissipative resistors as in the link bellow.
https://www.digikey.com/product-search/en?keywords=KAL50FB1K00-ND
I was wondering about the behaviour of this kind of resistor...
All what I will say needs to be checked/confirmed because I am also a 'Newbie' in electronics.
Ok. I don't know what signal generator you have but usually they are low power TTL output signal. Which means that they can't give enough current for switching ON and OFF high current transistors. Why...
You can go on digikey or mouser or Farnell website and they have a filter tool that will help you to find your mosfet. Just a question, why do you want only 5v on your gate?
I don't understand the question but if it's about the magnetic field orientation, it depends on the current that goes through the inductor. (Look the right hand rule)
Here is a gif that shows direction and polarity in LC circuit...
