Fascinating Les, I wish I didn't have to eat and sleep just explore all the possibilities. So many tests to perform. I wasn't aware of the TPU video's, thanks.

I'm thinking along the same lines...

Cap Dump

Ron,

Question...

What is the reverse breakdown for the IRFP260 FET?


Thanks, Brent

Brent,

Here's a schematic that shows how to connect the FET. I verified again that the IRFP260 FET (just 1) works on my machine and runs cold to the touch, no heatsink. Be sure to hook up an...

I may have discovered why your K12A is not working. Data sheets don't seem to be available for that vintage of Douglas Randall SSR's but I was able to piece together some spec's on the...

OK we have to figure this out. Its not dumping anything if your cap voltage is rising to 100V. With your size coils you shouldn't be having any trouble flowing RE through the FET side of that SSR. ...

Thank you. That's exactly what I'm saying! With our 3 coil monopole wheels we can get a little over 1:1 but by adding the energy from the re-gauging motor in generator mode (or even another...

Thank you for your last two posts. Good insights and observations.

To me the FET inside the SSR is just a conduit through which the radiant energy (RE) flows. It doesn't have to...

SSR Cap Dump

Well after all the messing around with different cap dump circuits it turns out that John Bedini's SSR cap dump works the best (for my wheel anyway). Is anyone surprised? He did say it was simple...

Excellent! What circuit are you using and what is your cap dump rate?

Thats a good start. I will also try covering coils with a metallic sleeve as Ed L. showed (soft iron, I think would be best). My SSG has one coil with seven power windings and one trigger wire all...

Hi Les,

This NE2 trigger circuit works great with a 36V system and its simple and definitely dumps current. I've tried several sidacs and they tend to stay on too long and cause problems but...

Brent,

I think the SSR inside the box in JB's video is a Douglas Randall K08A with a FET switch and probably rated for a load voltage around 40-50V. The FET breakdown voltage is not listed on...

Les K.

Add a small load to the shaft of your wheel and that will make the hall adjust a little less sensitive. The load represents the regauging motor load on JB's wheel and is necessary for...

Patrick,

When you get ready to run your big wheel try this cap dump circuit. It's similar to what John K posted awhile back just different components. It works well on my 5 foot wheel.

48V Cap Dump

Brent,

The 48V level of the cap seems to be where the opto coupler FET in the box breaksdown and dumps the negative spike to the battery. I don't think the 48V was picked as much as thats what it...

John K,

It looks like a Douglas Randall Model K08A or K12A. Its hard to tell. The K08A is rated 8A and 32VDC on the load side and the K12A at 12A. Each is described as a bipolar transistor...
