Opto-couplers are orders of magnitude slower than BJT/FET/IGBT

For example:

Code:

Parameter    H11D1    IRF610
td(on)         5uS        8.2nS
tr               2.5uS      17nS
td(off)         6uS        14nS
tf               5.5uS      8.9nS

E= V^2*C/2
30uF @ 550v is 4.54 Joules, you could probably scale that up a bit


However, if your inductor is lacking impedance, your switch might be seeing 550 Amps at t=0 and ~10 Amps at t=120uS... Yeah.. most silicon switches affordable to hobbyists aren't well suited to capacitor discharge.. mmmmmm... Thyratrons .... :drool:

-Edit-
The following circuit could be modified to drive a low-side insulated-gate device, safely and very fast!
High-Side Gate Drivers

Hi boguslaw,

I checked the data sheet for your mosfet driver and it looks like you have everything drawn up properly. I would make R1 and R2 about 1K to start with to limit the current and see how everything switches. If you do not get full on and off like you want you can try lowering R1 a little and then R2 if you need to. I would not go lower than about 100 ohms on each of them because you could burn out the opto coupler or the mosfet driver.

Good luck,

Carroll

Relaxation Time: The time it takes for the free electrons in a conductor (or material) to reach the skin of the wire after potential is applied, is, of course, called the relaxation time. During that time, the free electrons in the gas are "trapped" insofar as producing current (dissipation of the potential) is concerned. However, immediately after the relaxation time ends, current begins and dissipation of the trapped energy begins.
In copper, the relaxation time is incredibly rapid. It's about 1.5 x 10-19 sec. However, in quartz it is about 10 days! So as you can see, we need to get somewhere in between these two values, and so we will have to "mix" or "dope" materials. We must get a sufficiently long relaxation time so that we can switch and collect comfortably in cycle one, then switch into cycle two for dispersion of the freely collected energy in the collector. However, the relaxation time we get must also be short enough to allow quick discharge in the load, as soon as we switch the primary source away from the collector. Actually, we need a degenerate semiconductor material instead of plain copper.

that is from Tom Bearden's Final secret of free energy.

Could a very thin PVC Fluid Hose filled with salt water serve as a conductor with slow relaxation time?

I mean, 100 ft of 1 mm PVC FLUID HOSE filled with salt water. winded like a coil. and then we pulse that water coil in bedini fashion.

I am too crazy? or it is a good idea?

best,
