Re: New PSUD-3 now in the works !


 

? Several emails between me and? Duncan Munro..who is also a ham.? ?All these anomalies are being fixed as we speak.? ?Also, if u do something stupid, like use less than the min inductance for a choke, on a choke input filter, it will let u know asap.

I also asked him to include more stuff, like? express? ripple in db down, which is what's used in the commercial world, which makes more sense? vs? ripple %.? ?Also what? might be included is 3 phase? setups, with 3 x common rectifier configs .

Filter ringing will also be addressed.? ? We also need a better stepped load feature, that? depicts a dynamic load better.? ?There is a bunch of more stuff? being looked at.? Stay tuned.? new version will be called? PSUD-3.? But it won't be ready for a while, with all these extra features and other fixes being in the mix.? ?He also has? LTspice, which does depict stuff a bit more accurately..and does stuff like factoring in diode C etc.? ?New version will also include resonating a choke..+ stuff like? RC snubbers across a choke and xfmr sec, etc.?
Hams won't use most of this stuff, but the DIY tube audio guys sure do.? ?As is, PSUD is the only thing I have found that will depict rms current into a filter cap...which is? typ? 2.5? X? max plate current.? ? Most of these rinky dink modern day 200 /330 uf caps are only rated for 1.5 to 1.75A? ripple current as is.? ?Which is barely up to the task? for? tube that sucks? 800ma.? ? ? ? ?
