Need the topology for a current to current SMPS, not voltage to voltage SMPS

I rarely deal with either buttons or shoe laces. Both are archaic wastes of time.

Okay, gotcha. Well, at 100% duty cycle, your minimum output power would be about .05*5 or about 250mW with a 100R load. Will your load resistance never get higher than that?

changed the circuitry so the the current supply is around 0.335 and the compliance is around 1kV, so a dead short still stops most of the power.

It's just I'm used to 'opening' a circuit to stop power, but opening the circuit takes everything through horrific power levels on the way to 'OFF', other parts get the brunt. so a short should work - especially a switch to gnd with less than 1 ohm impedance.

How horrific depends on the time it takes to full open. Burning off 335W for a few microseconds isn't such a big deal.

Don't like pull over clothes of any kind. I have a few pullover sweaters and sweatshirts but I rarely wear them. I really only need something covering my shoulders and arms. Cardigans work, but aren't currently in style so they're impossible to find.

Without laces, my shoes would fall off. Shoes without laces wouldn't go on.

Me opposite. T-shirts and sweat shirts.

People like Adidas used to make good velcro shoes, but they don't any more. So I buy running shoes and replace the laces with Yankz elastic laces, to convert them to slip-ons. Added advantage is that they don't come untied.

but when left OPEN there are components that still get huge amounts of wattage AND high voltage! So, getting to OPEN fast just means the full brunt is applied sooner not that you pass through a 'danger' zone and then you are ok as it goes totally open. OPEN is the ABSOLUTELY worst case condition for all those parts.

The lowest losses and lowest voltages on the components occur when trying to drive a dead short. mV and mW

Those are neat. I'll have to try a set or two.

Yeah, if it still wants to dump current at 1kV "open" isn't going to work. I thought the thing was allowed to turn off in that case.

Without knowing what exactly you are doing all we can do it take potshots at the problem.

Wow, that'll come in handy. Thanks! ;)

Easier to move, than clean? ;-)

I bought a couple HP 3455A meters that need repaired. Looks like it'll be loads of fun, and they have IEEE-488 interfaces!

Something like that. Mostly it's just always being in the middle of several things at once.

When i run a batch, it is almost like a couple of holidays a few weeks apart. That is the main reason it is a hobby. Whip up the brew, go back to electronics and whatever else for a couple of weeks, bottle it up or set it up on tap or most likely both. The bottles are for friends that can't just come over any time. I do require that the bottles be returned to use again.

Yup. It was filmed in his house.
