Hi Andy, Thank you so much once again. It already worked with the first approach in your earlier email so maybe I can try this one if a new oppurtunity comes. Best regards, Eric

Hi Andy, Thank you very much again! It works! Really appreciate your perseverance to help and support us newbies to LTspice XVII. Best regards, Eric LTspice@...> wrote:

Hello Bordodynov, Thank you for your advise. I checked it out but was a bit confused how and where to save it as it doesn't have the "and gate" icon for a symbol. But thank you very much for taking

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!!
