Highish Current/Lowish Voltage Rectification


April 22, 2014, 6:14 pm

Hi all, I have a welding transformer that produces an output of either 50V AC or 80V AC (open circuit voltage) at a range of currents of up to 200 Amps. I want to convert this to DC, preferably b... Read more »

Does this thermodynamic invention make any sense?


April 22, 2014, 6:12 pm

I'm wondering if this makes sense You have an oil lamp as a source of heat. Then you have a thermoelectric generator coupled thermally to it. (Could be a cooler run backwards.) then you connect th... Read more »

Triac vs MOSFETs for AC switching


April 22, 2014, 5:45 pm

I'm designing a switch (basically a SSR) for AC 110V, 60Hz. Does anyone kn ow if it's better to go with a pair of FETs or with a Triac? My design has to be able to withstand a short circuit curre... Read more »

PING Kevin Ayward


April 22, 2014, 1:28 pm

Kevin, As you are a simulator expert, I have a question for you... If I have a _bounded_ source driving an Algebraic multiplication, is the result bounded (in simulators :), or should I bound the m... Read more »

test gadget


April 22, 2014, 1:28 pm

Imagine a box with a USB interface, that is full of DACs, a mux'd high-quality DVM, a bunch of logic i/os, I2C and SPI, some SSRs, a few programmable power supplies, all easy to control from variou... Read more »

Survivalist Electronics and Technology


April 22, 2014, 12:34 pm

So, I am opening this subject, since I have not seen any disciplined approach to the subject. What happens with an errant meteor or that awkward emp goes off? Can electronics be protected? Does... Read more »

Test equipment auction


April 21, 2014, 7:15 pm

I know some of you always seem to be on the look out for test equipment. I got this email today from Bentley's Auction for 300 lots of test equipment. Might all be crap, might be a good item in th... Read more »

Stepping multiple parameters in a simulation


April 21, 2014, 2:47 pm

A question presented on the LTspice list by John Woodgate prompted my answer, which may be of interest to other LTspice/PSpice/whatever users: Here's an extreme example of multi-parameter stepping... Read more »

STmicro acceleration/magnetic sensor LSM303DLH == LIS331DLH + HMC5834?


Just had a look at the LSM303DLH datasheet and had a déjà vu ;-) It looks like ST has simply put a LIS331DLH and a HMC5843 into one package. (The HMC lacks the built-in voltage regulator) All data ... Read more »
