Helmut, I am plotting V(N002)/I(R11). The plot profile looks OK, but, as mentioned, the phase is off by ~45 deg. Thanks and best regards, Jerry

Hello Jerry, I have opened your uploaded circuit, but I don't know which voltage or current I should look. I am very interested to see the paper where this circuit comes from. Please show a link and

Helmut, I uploaded the .asc file. 20181123_exact_Paper_LTspice. Thanks for all that you do! Best regards, Jerry

Hello, Your circuit requires 3 important changes. The three V-source used as gate driver has to be connected to "Vout" instead of GND. The series resistors of these V-sources has to be chnaged to e.

John noted, "Andy, I don't think a max time step was set, only a delayed start to saving data." Oo, right. My dyslexia (don't we all have a little, at times?) read it as ".tran 500m 0 20m". Nevermind

I agree; the simulation runs OK. But you would see much better if you gave the DC outputs different labels, Vout1, Vout2,? Vout 3 and simulated from zero time to 50 ms. You can then change the labels

csizikem, please don't use those long URLs that begin with "xa.yimg.com". They are temporary, and might work only for you. Instead, just let us know that the file is named "3ph_rectifier.rar" and that

No-one can tell by extra-sensory perception. Upload your .ASC files AND all the other files required to run the simulation as a ZIP archive to Files => Temp and then tell us you did that. Besides,

Hello Jerry, Maybe you have you started at a too high frequency with your .AC simulation. Have you really plottted V(out)? I ask because some users wrongly plot V(out)-V(in) instead of V(out)/V(in) or

Group, I have a circuit consisting of a 12-unit, non-uniform RC ladder. The Bode plot of the input impedance shows a phase shift of 0 to -45 degrees, but the expected result is -45 to -90 degrees. Is

Dear All! I made a rectifier with thyristor (3ph). If I simulated just one phase, then all right. If I simulated the 3 phase, the the simulation don't work. Any idea?

Thank you, Helmut. I see. I will try to report it. Thanks again.

Yes, the file is there, but it cannot be opened. I just simulated a sine wave to check it!!

thanks for your answer

Hello, I agree. The FFT-file created by MAC-LTspice has been corrupt. The problem is with the latest version of MAC-LTspice independent of the MAC-OS version. I tested the FFT with the jigs-example

Yes, there are many models of black holes, but none, I suppose, that are compatible with LTspice! No existing models are considered satisfactory. More research is, of course, needed. There is a good

Eric, there is another way to have the symbol automatically load a library file. That is to use the ModelFile attribute. See the same Help page as in my previous reply, as well as this one: Schematic
