I had used NG-spice for circuit simulation for a while but it get convergence or "Gmin step too small" error easily.
After google search for a while, i found Xcye simulator. It is opensource as NGSPICE but look more powerful. Is there anyone use xyce before ? Is Xyce really no "Gmin step too...
I thought you are driving primary as flyback converter. Vin*D/(1-D)=Vout.
With 10:160 turns ratio and 50% duty, you can get output 16 times of input only.
The reason why you get 2.5KVDC because you get the HV by leakage inductance of transformer, only a very small load at output will cause...
what instrument you used to measure the voltage?
what is its internal resistance ?
when the 4 circuit connected in series, have u measure the voltage of each circuit? are they have same reading?
ac analysis measure the frequency response of a system. freq response usually use 0db(1v) as reference. eg , gain of amplifer, filter or system usually in express in db. use 0db is easy for reference
are the ouput coil connect to cap directly without any diode? if yes, it just like a LC tune circuit. ouput step up by LC resonate. output is ac.
In series of transformer ouput will cause output inductance changes, you have to adjust the cap such that LC resonate freq same the apply freq...
I had just downloaded the jumbocad. I want to simulate my flyback converter. However its magnetic core model didn't work.
The jumbocad schematic provide a lot of functional block such as gain, differentiator, integrator, multiplier, limiter, voltage & current source.....etc.
I want to create my...
It still not easy understand. Could you give me an example how to estimate the core loss base on the "nB" on datasheet on https://www.epcos.com/blob/528850/download/3/pdf-n27.pdf ?
switching frequency 50KHZ, dB=150mT , what is the core loss ?
What is Hystersis Materials constant
I had donwload the ferrite core datasheet from EPCOS, there is a parameter call Hystersis Materials constant "nB". What it is ? How can I get the remananece Br ?

Hi,
I want to plot the Hysteresis curve of a ferrite base on Jiles-Atherton Model using java. From ferrite manufactuerer's datesheet, I can get the parameter Bsat, Hsat, Hc, Br, ui. How can I apply the parameters to obtain thouse parameters Alpha, Ms, a, k, c of Jiles-Atherton Model ?
Regards...
I had downloaded the datasheet from EPCOS https://www.epcos.com/blob/528850/download/3/pdf-n27.pdf,
I want to know the remanence Br of the ferrite, there is parameter name Hysteresis material constant "ηB" on table of Page2, could someone tell me what it is ? How can I calculate the Br from the...
Wu ! Thank all your information. That mean apply a AC source to a superconducting inductor, the charging current will be a DC current. right ?
Now come back to my transformer gate driver, I am headache because when I apply a pulse width signal the the input, the whole waveform output always has...
yes, i apply a ac source , 12v,100khz, 0v offset, to an pure inductor with inductance 500uH, transient start from 0-50ms, step 1us. start the simulation run and suprising find that the inductor current always shift above the 0 level. when i place resistor in series with it, the ac current will...
