pha0001 asked: "why did you take a quarter of the total primary inductance? Why not just half it?" Adding to what Vlad already wrote (which should lead you to your answer), it does depend on the

What's the equality between the ratios of the inductances and the number of turns? Vlad ______________________ ltspicegoodies.ltwiki.org -- holding, among others: a universal analog/digital filter,

Thank you so much!!! Things are starting to become much clearer now. If you don't mind, may I ask, why did you take a quarter of the total primary inductance? Why not just half it?

Hi Helmut, It's actually the X-axis I have trouble with - see "X-Axis different scales.jpg" in Temp. Regards Stephen. PS Mike told me (quote) "lock horizontal axis should do that."

Hi Helmut It's really the X-axis I'm having problems with - see "X-Axis different scales" in Temp. Top: Initial plot Middle: Set precise manual limits on time range Lower: Only one plot pane is

Quite a mess, as expected :) Thank you Andy, I think I have it clear now.

I was looking for an electronic "dash pot" for a solenoid and found the TI DRV10{2, 3} series of delayed-start PWM devices.? Downloaded TI's DRV103 spice file, looked, did a few sort-of educated

Thank you for the advice, Helmut.

I also tried .meas ampx MAX V(Out_1) I(V1) thinking I can plot the max of V(Out_1) vs. I(V1) I tried to do it by adding another directive .meas ampx MIN I(V1) for no avail. Any suggestions is most

Helmut Is there a way to optimize on 2 or 3 variables and plot results like you did? i.e. Ton Tperiod R of the inductor for example? Thank you LTspice@...> wrote:

Hello Sam, I have additionally uploaded your example with MEASURE to the Temp-folder. transformer2_meas.asc Best regards, Helmut

Helmut Thank you. That is really good. LTspice@...> wrote:

John, Andy, - I suddenly stopped getting any messages from the list about the same time as that change. Checked to see if somehow the group got added to the yahoo spam list, nada. - I did change to

Hello Sam, This is wrong. See the correct version below. PULSE(0 10 5u .1u .1u {Ton} 1m) .step param Ton 2u 10u 2u .meas ampx max V(out) Run the simulation. View -> SPICE - Error Log Right-mouse click

Hello, No. Most of the parameters are the same, but especially HSPICE has often additional parameters. I vaguely remember that Spice programs can have different equations to calculate Weff and Leff,

Hello, I don't understand your log-plot. May be you simple asked for the step response of RC-circuits. .param tau = 0.2 V = 5*(1-exp(-time/tau)) Best regards, Helmut

I've uploaded 2 files to the Temp folder: curve_exp.jpg curve_log.jpg To get the exp curve in curve_exp.jpg I used: Value: V=5*exp(7*(time-1)) in a Behavourial Voltage source. It gives an exponential

Hello, I am getting confusing hints from search results: .. So a mosfet "level" is a way to model a mosfet using a set of defined parameters. (?) There are many so called "levels" and there have been

Hello, You could use the command from the menu Plot Settings -> Autorange Y-axis The shortkey is Ctrl-y Best regards, Helmut
