Messages / Emails from the PSUD group
Hi, Message posts on this group are infrequent, however when we do have some messages going out there are a flurry of unsubscribes. Emails are not always welcome, and these groups default to sending an email for every message that comes in. If that is tiresome, or unwelcome you can reduce it or switch off altogether and still stay a member of the group to read the messages when you wish. Your subscription can be managed at:? /g/duncanampspsud/editsubThe choices are fairly self-explanatory.
- The default is "Individual Messages" which will generate an email to you for each message and each reply - this is too much for some people, I know.
- You can select one of the digest options which packages up a dozen messages and puts them in one email, or a daily digest that gives the whole narrative for the previous day in one email.
- There's "Special Notices Only" which will only ever be used if there is an upgrade to a new production release of the software.
- And finally, "No Email" which switches all the email notifications off. You can still log into the group and see the messages, and also post messages
Hopefully that information is useful and will allow you to get the right balance of updates from the group. Regards, Duncan

OK thanks. I'm busy with PSUD3 right now and it would not be sensible to do even very minor changes to PSUD2, simply because of the significant amount of time to run through regression testing across multiple systems. However... I have put a beta build 78 for Windows executable in the files area ->? /g/duncanampspsud/files/beta_test_filesYou will need to copy to your program folder and run from there, it's not packaged, and doesn't have an installer. On startup for the first time it will take up 3/4 of the screen (not desktop) and if you resize it will save the settings on exit. When you start up again, it will restore the screen settings from the last session. Regards, Duncan

Hi Duncan,
Windows 10 Pro
Version??? 10.0.19043 Build 19043
I always check that I'm using the latest release before bitching...?
and I keep two rollback versions so I can test things that crop
up... as a retired programmer, it's professional courtesy...
Cheers,
- Ian

Hello,
I do wish the application either always started on the primary screen or on the last close screen.
It's most annoying to have it open in the middle of the desktop surface with multiple monitors, i.e. split between monitor 0 and monitor 1. It's probably ok for 1 or 3 monitors, but not 2 or 4

Re: Transformer primary voltage entry won't stay put on Mac version
[Allen]? The version I'm using is PSUD2 version 2.20 build 74. My mac OS version is Catalina version 10.15.7 from mid 2012
Hi Allen,
That's where I'm going to have an issue with debugging. I bought a Macbook Pro in Dec '19 to do some dev work for PSUD on, however it uses the very latest Big Sur operating system. Unfortunately, I don't have any other Mac hardware, and I certainly don't have any setup or OS going back as far as 2012. All I can do is check the software against my current system and try and reproduce any issues on that.
The? issue with the menu options moving about is one example of what I cannot check as the latest OS puts the menu for the active window right at the top of the screen, so I cannot really help with that one.
The other issue with the 120V being wiped each time, I can reproduce this on the Mac (it doesn't do it on the PC). This is something I can reproduce so will have a look at that this evening.
Regards,
Duncan

Re: Transformer primary voltage entry won't stay put on Mac version
[Paul]Windows PSUD2, I do not see a transformer?primary?voltage. Only secondary
Hi Paul,
There's a couple of built in calculators that allow you to work out the source voltage and impedance, one does rely on primary voltage but it's hidden away.
If you Edit the transformer, there are a couple of buttons with [...] written on them, the top one allows you to calculate the two parameters using a transformer offload voltage and regulation%. The lower one allows you to calculate the two parameters using line voltage, resistance etc. and it does rely on primary voltage to do the math.
It's the lower on that Allen is referring to, that's the one that is having behavioural problems on his Mac.
Regards,
Duncan

Re: Transformer primary voltage entry won't stay put on Mac version
Hi, and thanks?for getting back to me so promptly. Maybe toolbar is the wrong term. At the top of the the app it has File, Options and Help buttons along with the name PSUD2. This does not show itself unless I move my cursor all the way to the top of the screen and then it drops down in view but if I move the cursor down even a tiny bit, it retracts back up out of view. Again, maybe this is something to do with my macbook but it hasn't occurred with anything else. On the issue with the transformer primary voltage flipping back to 240, when I run the app on my PC, there's no issue and it stays set to 120 when I reclick on the transformer but not so with the mac. The problem with the mac is after I set it to 120, and click ok, it immediately reverts back to 240 even without doing anything else. Maybe it doesn't affect the ability of the program to calculate things?

Not sure about the toolbar issue, I cannot find a toolbar above the design area. Could you please let me know what version of MacOS you are using?

It will give a name and a version number, ?Also can you let me know what build of PSUD you are using which can be found from Help -> About.
The transformer voltage is set at 240 in a calculator screen, it's not saved anywhere and it just defaults back to the programmed settings every time you access it. I can amend it so it leaves the existing values for when you go into the calculator again during your current session.

Transformer primary voltage entry won't stay put on Mac version
I recently got a Macbook pro and downloaded the mac version of PSUD2. Only having a couple of issues I wanted to run by the group.
1. toolbar above the design area stays hidden until you move your cursor up to the top of the screen then it appears as long as you keep it there. Maybe this is just an Apple issue but wanted to check with you as well.
2. When I enter the transformer primary voltage of 120, it enters fine but when hitting the OK at the bottom of the block and reopen, it keeps changing back to the 240 volts. I've tried removing the program and reinstalling but still does the same thing every time.
Thanks!

Van: [email protected] < [email protected]> Namens Duncan Munro Verzonden: maandag 23 augustus 2021 10:00 Aan: [email protected]Onderwerp: [duncanampspsud] PSUD News ? Hi,
Thought I would string a few words together about what's happening right now and what people can expect in the future from PSUD.
PSUD3 is still very much on the go, with a number of key features being implemented:
CODE COMPLETED - Rectifier database built into the software
- Rectifier curve fit to make your own from datasheets (Solver)
- Totally rewritten calculation engine with much better accuracy
IN DEVELOPMENT
- New "splitter" filter to allow your power feed to split into two or more threads, each with their own filtering and load
- Ability to mix rectifiers within a supply (e.g. bridge with 2 x vacuum tube rectifiers and 2 x solid state)
- Schottky rectifiers
- Lots of charting improvements
- Dozens more minor things
Hope the update is useful. I have a day job and an impending house move so don't get as much time as I would like for this, however I do try and spend some time on it each week :)
Finally, a couple of screen shots of the new rectifier database showing how data sheet information is used to create or validate a rectifier model.
Regards,
Duncan

Many thanks. ?I love this program!

Re: MacOS Install error - "the following disk images couldn't be opened" reason: no mountable files systems
I am on OSX 10.10.2 and have the exact same problem, is there some compatibility issue with older OSX versions or perhaps the file is corrupt ?

Re: MacOS Install error - "the following disk images couldn't be opened" reason: no mountable files systems
? Hi Scott.
In my experience that error usually means the download is either corrupted or incomplete.
I’d try downloading it again.
