i need the help of a real good professional who really is top of the game.
we are trying to perfect the design of our own a SMVS with the requirement input 110VDC, output 17VAC 3A through to a simultaneous phasing of 9.6VAC at 4A in the higher harmonic region (theta 7.3). as you know the control of the SMVS operation is critical in getting the phasing correct. we look at the STELLARIS M4F series and think it can achieve the mass inertial calculations in real time. has one of you guys got any experience of the typical design layout with this processor using Keils RTX?
SMVS?
i dont do waffle. if you dont know, you cant help.
110VDC sounds strange. That's neither a regular supply voltage anywhere in the world I know about, nor something used in industry applications familiar to me (though I have to admit my background is automotive).
Don't do waffle if you don't want to.
I can only guess that you might mean Switching Mode Voltage Supply, but I have never seen that specific acronym and I don't like to assume. Especially, since I don't recognize the source voltage, making it possible this is a special device that have been given a field-unique name.
If you find it pointless to make sure nothing you write can be misunderstood, then that is up to you - and it would then also be no reason for us to make sure what we write can't be misunderstood.
stop fishing. if you did know you would not need to guess or assume anything.
So show how many references you see on google - that should give you an indication how well-used acronym you have selected...
But there are a huge number of very specific acronyms in use for different designs of PSU, as separate from the general concept of switching power supplies. Some terms are even so specific that they are only used by specific companies.
The generic term would otherwise be SMPS - not SMVS.
it is irrelevant how many references are seen on google.
it is also obvious you cannot help.
And it's obvious you are a ***.
Question is - did it take hard work?
oh dear. looks like a nerve was touched.
fyi i'll let you know that a cross post has found me some help. from someone who is aware of the subject.
@gally Mimu
Why are you so aggressive?
aggressive? me? no.
who was the one who felt the need to use a profanity? the expert? hah.
Good for you. How about linking when you cross-post? But maybe you don't spend much time caring about wasted time from activating multiple forums to solve your problems? You seem to be that type.
A Somewhat Mediocre Voltage Supply can be built using the appropiate controller chip and a couple of mosfets. I see no reason to replace the dedicated controller chip with a microprocessor, the dedicated chips do a much better job.

PS I HATE unexplained acronyms. Read an article in the widely read EDN which may start like this; " this product consist of a PCB (printed circuit board) which ...."
PPS To qualify for having EDN sent you must check "involved in electronic design" EDN is NOT "Popular Mechanics"
The processors are great at generating PWM output but if the feedback loop dies (or isn't fast enough), real interesting things can happen. That is where a dedicated chip shines. It responds quickly. Especially when there are short-circuit conditions to react to, or impulse loads.
looks like stupidity likes to follow ignorance. you discuss the subject when you don't even know what the subject is. remember i originally said i was after someone who was top of the game. you may think you are, but the more you write just shows how far from that point you are. the only ones you kid are yourselves.
