Has anyone seen this - Voltserver: "Digital Electricity"

<< < (10/20) > >>

Cyberdragon:
I'm not watching an hour long marketing vid. It's 300V! What magical safety are they using? I've been hit with 300V across my hand before and it hurts like hell!

Your pic shows a triangle wave (I see now it doesn't cross 0V, meaning only a standard smoothing cap then). I thought this tech used square before that. So why is it a triangle in the pic? You said yourself it wasn't square too!

Could you please tell where you see square waves? Waveforms shown in patent applications are far from square wave. I don't think that they are so stupid to do such an simple mistake - make product with EMI issues.

So, if it's square, you'd have nasty EMI. Otherwise, if it's triangle (or some other shape), how is it "digital" and "packetized" then?

Heard of slew rate control? - Those guys are not beginners. They for sure knows what is needed to be within EMI/EMC regulations. So all your "it will make lot of noise" is just... "lot of noise".

[edit] Digital and packetized? - Easy. V.90 modems transmitted 56Kbps of data using audio (!) band. Those Voltserver "packets" are 1kbps average or so. At given duty rate it is max 8Kbps. Not even close to RF interference   :-DD

Frauhofer would not put their name in shame, but yet they collaborate with them:

Muttley Snickers:
Our cabling and wiring standards down here are pretty much based around separation from other services and the reference points are particular voltage levels or potential differences, mandatory separation distances, protective barriers or insulating conduits are all relative.



Cyberdragon:
What's shown in your pic isn't slew control. Unless it went so far as to unsquare the wave entirely (as far as I know it's never that dramatic). It's also for data, not power, so maybe at these levels it would have to be dramatic. This still doesn't address safety either! And now it's just added even more complicated circuits when it could all be avoided by just using DC in the first place!

1Kbs! :-DD You want to send data at dial-up speeds to what exactly? You know, there's this amazing invention called WI-FI! :palm:
