I've read a couple of papers on these particular SITh devices, and
likewise been unable to find any actual data, from NGK or anyone else.
This lead me to the conclusion they dont really exist in production
quantities. Hopefully I am wrong. Static Induction devices are
intriguing in that they offer (in theory) a lot more GBW than anything
else on offer, but their practical development seems to be taking ages.
Mind you, in 1993 I started looking into MCTs, and they havent really
gone anywhere either. Apparently the clever jap that came up with
SI-devices wasnt believed by many professionals, for a long time.

The static induction transistor was a normally-on device that I only
ever saw marketed by Sanyo and Tokin. Apart from it's self-biasing
qualities, I could never really understand what the fuss was about, as
high conduction impedances prevented their use as an efficient switch.

MCT and MTO devices are used in kilovolt, series and pulse-forming
applications (as are their bipolar counterparts), where high frequency
switching is not anticipated. Tq hasn't gone down, but control power
and flexibility has improved.

If you lived north of Shea Boulevard you didn't live in the "Town of

Hi Mike,

Check out whether you can obtain large transformers in a more popular voltage, such as 24V. Then two with the secondary in series might work.

There are also a whole lot of them with two 12V windings, for car battery chargers and stuff like that (that way they saved two rectifier diodes which probably were more expensive than copper). These would also produce 24V when taking the two outer terminals on the secondary. Those kinds of transformers have a lot of oompf and might be just the ticket. Some of them are meant to produce a couple hundred watts or so for battery charging but also a whole lot more for short bursts. These bursts were meant for the situation where you didn't have time to wait for a reasonable charge but wanted to crank the engine right away. I have one of those "starter" chargers and it cost around $30 at Sam's Club so the heavy transformer in it must be cheap.


Regards, Joerg

Bill Sloman, Nijmegen

Thanks for your insight. I have conversations with PhD's that are
going to vote for Kerry - and other PhD's that are going to vote for
Bush.

You do have to be moderately intelligent to get a real Ph.D., but
integrity is optional (if desirable). If I had to have business
conversations with boorish Dubbya supporters like you, I'd be sorely
tempted to keep my real political opinions well disguised.

Do you REALLY think that EVERYTHING Kerry has told you is the
truth? If so, you are one gullible sonofabitch. Let's be realistic
here, there is spin going on from BOTH SIDES!

Like I said, the real world is a little more complicated than you seem
to think. The fact that I think that Dubbya is presenting an
overly-optimistic and ill-thought out strategy does't imply that I
agree with everything that Kerry says.

For the record, I don't think that either candidate is silly enough to
use outright lies in their presentation, though the Bush camp does
appear to be spreading outright lies about Kerry through Karl Rove's
backdoor operations - which appears to have sucked in uncritical
right-wing nitwits like you.

Both candidates are obviously spinning the truth as hard as they can,
and the electors have to read their comments very critically - not one
of your obvious strong points.

As I said, I'm not volunteering to try to educate you - I'm really not
that good with slow students, least of all with those as bumptious and
obnoxious in their ignorance as you are.
Mr. Sloman, I've denigrated you in the past, based on my opinion of
my perception of you as a supporter of socialism.

But evidently, you live amongst a populace amongst which socialism,
in the form currently applied in your circumstance, works.

And I would be one of the last ones to argue against a philosophy that
leads to the least pain and suffering.


Thanks,
Rich

If I use a RC circuit? what values?

If the frequency is constant, then the RC depends on the frequency.

- Yes, the freq is going to be constant.
System chosen depends on the phase stability required
Long time ago I work on a unit used to correct the differential phase

Later I design a unit used to convert black and white text to color. I

Sorry I forgot, I am trying to obtain 2-4ms bi-phasic square pulses from
the current source (isoalted events). The resistance (500ohm to 2kohms)
values are guesstimates based on experiments done in the past (the
resident expert on this topic is
on vacation at the moment). Also, I saw some of the other suggestions
with supply voltages around 40-55V, I dont think that I will be able to
obtain sources above +-15V for the supply.


You also stipulated that the muscle be grounded, and that you might need
to drive 10 mA into 2k. This is impossible, I believe, since 10mA * 2k =
20 Volts.

snap


Anyway, If you are only going to have +/- 15 Volt supplies, and you only
need 10 mA, I would think you could work something out with op-amps.

For example, I still think you could use a current sensing resistor with a
difference amplifier across it, and take the output of the difference
amplifier back to the driving op-amp. You may need to use rail-to-rail IO
op-amps all around.

I don't know, maybe the offset voltages and stuff would add up and kill
you. I'm not going to do the analysis. ;-)


years ago I built a circuit that does exactly this, for a
(+/-10V)/(+/-20mA) analogue output circuit for a drive. The basic
circuit design was my techs, I just worked out the equations and
calculated the relevant component values. The circuit did work, in much
the way you suggest. A diff-amp sensed the drop across a small series
resistor, feeding back to the input of the voltage gain stage and
thereby controlling current - a current-limited voltage source. There
was a bit of stuff in there to switch between V & I out (actually that
was a real pain, we needed the low Vf of a schottky, but the leakage was
a huge problem and we were too tight to buy a good schottky, mostly
because having a single smt part is not cost-effective)

We built quite a few of these (5,000 or so), but what we found in
practice was the diff amp made a great resistor mismatch detector. Using
1% parts throughout, our overall tolerance ended up about +/- 7% IIRC.
We didnt want to throw away so much dynamic range for s/w cal, so we
re-designed the circuit as a voltage-limited current source (the
modified howland circuit) ie the topological dual of the suggested
circuit. The modified howland circuit is a piece of piss to analyse, and
worked a treat - tolerance dropped to around +/- 3% which pleased both
the s/w and production people immensely.

Cheers
Terry
[snip]

Heh. My notes from electronics 101 b do mention that the diff amp is
VERY sensitive to resistor mismatches.

Anyway, I'm giving advice outside my area of experience, so I should just
shut up. ;-)

Thanks for the information, by the way.

regards,
Mac

ps, if a circuit is a "piece of piss" to analyze, does that mean it is
hard to analyze or easy? Or something else?

Get a clue, moron. What you have here is your basic HE storage facility
and this one was a big one- over 70 bermed storage bunkers and numerous
outbuildings. The estimate is 40 big truckloads- and difficult for a
move to go undetected under the surveillance of our satellites. This
particular facility should have been on the top ten list of strategic
sites to watch in Iraq, but because of the total incompetence of the
military and political planning, all forms of traditional "enemy asset
management" operating procedures were abandoned on the promise of a
world class charlatan by the name of Ahmed Chalabi, and two world class
dupes by the names of Rumsfeld and Wolfowitz, that the Iraqis would be
dancing in the streets and cooperating in every possible way to assist
the US in restoring control. That damned RDX is tops for a very high
yield HE- they say that only 1/2 pound was used to bring down that
flight over Lockerbee that killed a few hundred servicemen. The other
nice thing about these compounds is that they make beautiful primer
material for more readily available improvised explosives- I hear that
artillery shells are popular now. But don't you worry about any of this
stuff, softy. You are a good 10,000 miles from any of that action. Just
snuggle up to a good book by your gas simulated log fire and sip your
latte- the US has plenty of dupes they can exploit to take the brunt of
the damage long before anything comes your way. All you need to do is
see whose explosive detection device is the hottest seller and maybe
invest some dollars for a profit, eh?
"U.S. troops did not conduct a detailed search of the compound nor did
they try to prevent looting" "No material under IAEA seal was found,
but Pentagon officials said the troops were not under orders to conduct
a thorough inspection."

"Pentagon officials acknowledged there was a window of about six weeks
after the invasion of Iraq when the stockpile could have been stolen
from the sprawling facility near Baghdad."

Dozens of locked bunkers were not inspected for their contents at that
time, so any assertion now that they were empty then has to ring hollow.

"Pentagon officials admit the facility was not completely secured between
April 10 and May 27, but many U.S. troops were in the general area."
"Deputy Secretary of State Richard Armitage said it 'looks to me like
somehow the multinational force didn't stay on top of this.' "
