Hi What effect to inductor/transformer building does Ctrl_r mean in the physical sense? In the example of Files/Temp/ transformer.asc L1, L2 and L3. how can I build this home transformer project to

sunder, The model is not well behaved, but it does work. Note that the link you gave says to use the alternate solver. Sometimes this solver can handle bad models that the normal solver has trouble

Hi Fellows, Hope all are doing well. I am trying to simulate basic igbt switching cercuit ( not yet with any specific model) so i found a basic circuit in file session of this group. It worked but its

Hi I've been working on this since the post your referring to went to the wrong group...:-/ Anyway... I was able to get the macro model working. I was about to ask someone if they could test the model

Hello, I wonder which schematic you use. The example F40WW.asc from the Files section doesn't need any extra file.

in the Fluorescent lamp model F40WW Can't find " p_smcj30.lib" in the include statement on the schematic and what is it?

Hello Sam, A transformer can only transport AC voltage and current. Thus the overall DC(average) voltage and current is always zero on the secondary side. Best regards, Helmut

Hi In Files/Temp/ transformer.asc Please help me understand why V(Out_1,Out_2) is going to negative numbers, I expected to see it from zero to 40v and back to zero, since plotting V Out_1 looks like a

You hit the nail again, Helmut. Gracias!!

The lack of such information suggests that the transistor might not be a good choice for this use. Jim Wagner Oregon Research Electronics

potrstuvich, The data sheet specifies the gate drive voltage, Rg, Id and Vds. A MOSFET is almost always specified with an inductive load which means the load current is essentially constant during

Hello Augustinto, There are two problems in your circuit. 1. The offset adjust circuit only works with a very few hundred milli Volts. See my test circuit. Analog multiplier 03_Vadjtest.asc

You can get some idea of the accuracy by examining the Vgs during the switching interval. If Qg is similar to the datasheet, then Cdg is correctly included. Losses in capacitance will also reflect in

I run across the schematic shown in page 13 of the RC4136's datasheet (uploaded). After 3 days trying to have it "working" in LTSpice (uploaded) I realized I need help. I tend to think I know the

Hello Cristian, The zip-files are in the Yahoo group LTspiceFiles. See the link below. https://groups.yahoo.com/neo/groups/LTspiceFiles/files/LTspice%20Files/

I can not download the file " Zip-files with all files from this group". Any help is welcome . Best regards Cristian
