Hi, you just measure one half. As you say, they are likely to be different; I would recommend measuring across both (red to red) and dividing by 2 for our purposes (both volts off-load and ohms).

( *red-ct-red* )? For full wave rectifier, do we enter the measured full ( *red-red* ) Secondary winding's DC resistance into the Secondary winding resistance field of the Calculator?? Or, do we

Regarding the offline transformer voltage to use. When I have the actual transformer, I measure the actual secondary open circuit voltage. With the transformer already in the circuit, which I think is

Hi Jonah, The thump is to be expected - the CLC filter is a resonant item. Solid state rectifiers apply power straight away and the sudden increase in voltage to the system causes the CLC filter to

Hi Duncan, Thank you so much for your thoughtful response. I thought I was going crazy, glad to know it wasn't just me. I wonder what that thump is all about? That said, the programs is wonderful and

Thanks for letting me know about the other channel, it was in Japanese, but I should have done the decent thing and waved Google Translate over it, apologies. I've keyed your schematic into PSUD2 and

Thanks for the clarification regarding off-load voltage and rated voltage. About the current draw... the schematic is for a stereo amp so I estimated around 96mA for two 6V6 and two EF86. The arrow at

If you right-click on the rectifer area when it is lit up, it should allow you some different choices. Regards, Duncan

I can see a couple of potential issues: 1. The transformer voltage should be the off-load voltage rather than the rated voltage. If you can't find out from the transformer manufacturer, try taking the

Hi! I'm new to PSUD and practicing on a model of an existing circuit. For the life of me, I can't get the voltages to agree. All the values seem to be right but the voltages are coming up considerably

I do not understand how to change the default bridge rectifier to a full wave. Trying to get my first PSU designed Roger

Hello Thanks to group members answering my previous Q - adding sections and solved by tapping on a Mac trackpad (!)? Yep, I had no idea. However, and having reviewed the available documentation on

In the corporate world, I suffered with McAfee, Norton, AVG. As a developer, fewer install problems from MalwareBytes using customers, but that could be due to market penetration. MalwareBytes

Not to sound like a shill for Malware Bytes, but I've been using them for years, first the free version and then the paid version It seems to work well and doesn't seem to interfere with my downloads

Thank you for the reply.? For others who might be interested: turning off McAfee to install does work and the program works.? Until McAfee resumes.? Then it kills the program requiring a new

Apologies, I was about to reply but you have summed it up nicely Paul. Yes, for a few years MS throws an error message when installing uncertified software. I'll sort out the Microsoft certification

Duncan may be busy. I done some software support and know the usual questions. What version of Windows? 7, 8, 10, 12? "incompatible" MAY just mean that Duncan has not paid Microsoft to be developer

First post here: since updating my computer, the new download of spud doesn't work.? McAfee blocks it.? Tried on two computers.? On one it says incompatible.? On the other McAfee stops it.? The

Hi, You're going to need to give a bit more information. Did it: * Fail to download - please provide the link you used for the download * Downloaded but failed to install * Installed but failed to run

i tried to downloaded psu sofware but it dont works ,can you help me thanks
