Selfrunning cold electricity circuit from Dr.Stiffler

Dr. Stiffler,

Are you referring to your capacitance measuring experiments,

Your paper mentions three load resistors. I was wondering what the power wattage rating was on the resistors.

Thanks,
Paul

I'm sorry I thought you were asking about the circuit I last posted for the (slayer007) direction.

The load used on the boost cap testing was an electronic load TekPower 3710A and it is good for 150W and is fully computer controlled as it was in the testing.

Okay, looks like good measurements. I thought maybe the load was heating, and thus changing the load resistance, but it seems fine. It will be interesting to see how much capacitance my 650F Maxwell booscap has, when it arrives.

Dr. Stiffler,

Again regarding the cap measurements, I'm wondering how your caps would perform if the load was higher resistance. I have no idea about such cap technology, but maybe the cap *efficiency* is far higher at lower levels of current. Obviously the caps are rated at higher current levels then what you tested, but I'm wondering if their efficiency varies a lot with the current.

Mr. Lowrance

I would suggest you look into some of the references I have in the paper. Resistance will indeed play a roll in the measured capacity. This is why I did the study, I had a large disagreement with a boost cap supplier. The product was advertised as 3F and was stated to supply +200 amperes of boost for the bass component of auto sound systems, although when I told them their cap was no where near 3F they stated I need to use a 350+ ohm resistor to see the true value. Wait a minute, something is wrong here, right, +200J through 350+ ohms when cap is charged to 13.6V, bells go off here....

Found the study very interesting as well as the strange things one sees because the larger caps are really smaller caps in a series/parallel arrangement. Some very strange artifacts can be found.
