Regeneration and the Toroidal Power Unit

[eldarion]

Well this can be shelved too.... as i said before it seemed too simple to be true....

I wouldn't shelve it quite yet--give EMDevices a chance to clarify his input power measuring method, and confirm/deny that CTGLabs' circuit is the same as the one he has been working with. 
Personally, from what EMDevices has said, his input power measurements are correct.

As they say, the devil is in the details.

Hi,

If I was to go on just my DMM for the current input, its not so different than EMs.  But you can't use a DMM for pulsed measurements like this.

There maybe something else going on with EMs circuit, afterall what do I know?

It is just my personal opinion that if/when EM reads the current input using his scope which I am sure he will do later when he wakes up that he will see the same.

If he doesn't and he shows something else then that will be a nice surprise!

Perhaps Marco can also perform this input measurements too.

Hi Dave,
i have reread EMdevices posting and he said,
that he had a 1000uF smoothing ( lowpasfilter) cap
in his circuit, see here C2:


Also he has a cap in his powersupply unit and he said, that the input current
was a flat line, also on his scope.

So Dave, did you also use an input cap, so you could just measure
DC current into your circuit ?
I don?t see a big cap in your circuit board.
Please try one and try to smooth out the input current to a real DC value.

Many thanks.

Regards, Stefan.

Hi Stefan,

No, I did not, EM said it wasnt necessary and I was running from a 4Ah battery not an mains adapter.

But I will try this also.

Well Stefan and all,

I have connected again the circuit with 1000uF cap across the suppy, in this case the current drawn seems more inline with that off the DMM readings, however still we can see 1amp spiked current peaks.
