Hello, I have 6 semikrom SKKT 27/16 E modules* and a 28 mH inductor. I would like to know how I can wire them up as grid side rectifier bridge, an inductor DC link and a load side inverter bridge and connect a 400Vrms, 50Hz on the grid side (R, S, T) and to a small, synchronous motors on the...

Oh, my bad. I found it (Thyr_All.asy) from here: https://ltwiki.org/files/LTspiceIV/lib/sym/Robertugo/

Hi Baluncore, thanks for your reply. Please find the files attached.

Hello, I'm trying to simulate a 3-phase, 6-pulse Thyristor Bridge Rectifier on LTspice, but I can't seem to get the results. Here is what I have so far. Could someone please guide me on this? Thank you!

Thanks Baluncore, for your clear answer. Just out of curiosity, how did they calculate the "total impedance (sum of Thevenin and local line) = 8% ∠ 45° (expressed on a base of 240 V, 5 kVA)" I know Z =U*U/S = 240*240 / 5000 = 11.52 Ohms, but its not in %. And the angle, I'm not sure either.

Thanks for your reply. Can you help me solve for ( Rth + R1 ) and ( Lth + L1 ) ? Here is the reference: https://dokumen.tips/documents/effect-of-supply-voltage-harmonics-on-the-input-current-of-single-phase-diode.html Thanks once again.

Hello, I'm reading a paper at the moment and I came across this: We now apply the solution technique to a single-phase, 3 kW, 240 V ASD heat pump. The ASD has smoothing capacitor C = 4200 pF, (corresponding to approximately 6% ripple in dc voltage), and total impedance (sum of Thevenin and...
