Hello, I knew the program PSUD2 for quite some time and I have also used it a few times in the past. Mostly I just build my power supplies based on experience and trial and error.
It would be nice to do the dimensioning in advance through simulation.
How do you guys do this? Do you use PSUD2? How do you do it right?
As an example, I have a transformer with a secondary voltage of 240V (30mA) and want to use it to power a single channel microphone amplifier. Let's say the circuit (Gates SA70) draws 10mA and I want to filter the B+ voltage with a CRCRCRC filtering without regulation. I want the DC voltage after filtering to be 240V DC.
How do I set the load resistor (R4)? My gut tells me R4 should define the expected current flow, so my assumed 10mA, right?
Is this correct or nonsense?
