Hello, I searched a little bit with Google. Maybe this problem has to do with a mouse setting. https://www.hawkdive.com/cursor-moving-and-clicking-by-itself-on_30/

Hi richard. I made a solution to the problem of calculation, but the temperature of the transistor chips is zero, which is not correct. I do not like these models. To all, due to the complexity may be

I think you are right. I made a mistake. Sorry. sbb2.zip in the files area should demonstrate the problem. I will have a look at the help file you have refereed to. I have looked at similar files -

Hi Andy Thanks for your detailed response. Tomorrow, I will find time to optimize that. I see now the problem of an overloaded page... regards, Adrian

There are contradiction in real world ,too. If I just only study the textbook which contain lots math equations to describe the phenomemon of physics/electrics, etc. I tend to be confused, but if I

I have found and used the BSR202N model and test circuit from Tony(?) The test circuit worked - but in my circuit - I ma getting similar results to that from my original version of the infineon model.

Hello, Andy: The mentioned ideas was not from me, and not related to what I said about 'confidential'. Just a brief, sudden thoughts, but I certainly remembered that someone who had written some thing

Hello, LTspice has a phase comparator named "phidet". It*s in the folder [Digital]. The deafult output curernt is 100uA. This current can be set to any other value with Iout=xxx. See the example

Would anyone be able to direct me towards some accurate phase comparator circuits that I could build within LTspice XVII? Thanks

I still don't know what the Bv is for. Since it represents an unreal component, are you thinking about using it to experiment with an altered circuit, before designing that "alteration" using real

Hello Helmut, I agree in principle for transient simulations, but for DC sweeps it does make sense because the case to junction temperature difference would otherwise be zero, as you say. Regards,

Hello Tony, You shouldn't normally connect a V-source to the output TJ, because this pin is internally driven and shows the junction temperature. The output will be very different when you remove V4,

To upload, go to the web site, click on Files, scroll to Temp and click on Upload. Upload a ZIP archive (not any other sort) containing everything required to run the simulation, but not .raw or .log

I am trying to use the Infineon supplied Pspice model for this part (BSR202N). I've created (found) a 5 terminal symbol to suit the model, but it makes no sense in an LTspice simulation. If I replace

For example, (not adapted by me), the typically active PF controller makes the PF upto very high 99%, but after EMI filter circuit added, maybe some phase difference may be caused, those phase
