de.sci.electronics, You can have plenty of knowledge, first You will get canings :-) best regards Leo ...

There is something I would like different, but have always been so grateful for LTspice that I didn't want to rock the boat; In the schematic editor, it is not possible to pan far (or sometimes at

A collegue suggested that I put the parasitics of the kapacitor in discrete components in series, and that fixed the problem. Bug? /Johan

Hiya Mike Now that I have well over 100 different diode types in Ltspice I think that something that I would find useful would be a selector box for diode type "All, Germanium, Silicon, ZENER,

Schematic is uploaded, but the calculation is missing. Temporary P(in) is zero (as capacitor is already loaded and I(in) is zero.) That may cause a division by zero. hws

Methode how to calculate efficiency is missing. Please notice that R1 is not connected to gnd. I suppose you calculated like this: voltage should be: V(n003)-V(n004). Current is I(R1) so power is

Hi Micheline, Could you please post the circuit schematics, Symbols, and models and all relevant files in the Temp files of this group ? It is a lot easier with a schematic to troubleshoot. Best

Which german newsgrop? hws

Hi Helmut, Thanks for the reply. I already uploaded the file under name Pefficiency_analysis.asc. Please try to simulate the power in V1 and power in R1 since I am analyzing the Power efficiency

SPICE (and LTspice is no exception) can have additional shunt elements from every node to ground, added to help convergence. ?I've kind of lost track of exact details, over the years, but there can

Does anyone know what its means when LTspice give error: "Singular matrix: check node n002 Iteration No. 1" The circuit is made by AC voltage source, resistor (series with the voltage source), bridge

really, very kindly people here by http://tech.groups.yahoo.com/group/LTspice/ ... much more than in our german newsgroups :-) regards, Leo ...

I used to get strange differences between linear and log scales in earlier version of LTspice, though I haven't had any in the last year or two. They were never explained, but they certainly

It works, thank You Suusi for the lib-extension .... have all a nice new week ... best regards, Leo ...

great Suusi :-), best regards, Leo

Oops Sorry Found the problem and fixed it It turns out that I managed to miss the p from the grid plate capacitance so it went from 1.6pf to 1.6 farads hence the weird results I do wish the LTspice's
