Take your voltage meter (or scope) and measure across the D-S on each MOSFET. If the positive probe is on the Drain, the two voltages should be positive, and around 22V.

What is your circuit current?

I don't have to. I did measure the input energy to the circuit in both cases.

And there is a 0,36 Watt difference in the input energy with or without the other mosfet pulled.
And if your simulator is not showing this then your simulator is not correct vs real life circuit.

@.99:
Does the sim allow for substituting a really LARGE capacitor, say 1000 F or so, for the battery? You could model the battery's ESR and inductance with simulated discrete components. If so, one could charge the capacitor to 75 volts and let the sim run, monitoring the voltage at the board (with the stray lead inductances) and also directly at the capacitor itself, along with the other usual parameters. The first should show the negative mean power product. Then you could also show the capacitor's voltage over the time interval that the circuit runs.
Apologies if you have already done this. Perhaps if you have, you could post a link to the results. Thanx...

The .36W difference is coming from somewhere, but where? What is causing it, do you know? You said you wanted to know more about what is happening inside this circuit.

If you measure the voltage across the D-S of each MOSFET, you will then know if the body diode in either MOSFET is turning ON, i.e. being forward-biased to pass current. If they are, then you know that is the mechanism, and your assumption was correct. However, if they are reverse-biased, then you know it is something else.

Hint: My simulation is NOT oscillating.

Let's say your measurements indicate that the voltages are largely positive; what other mechanism(s) could be attributed to that 0.36W difference when Q1 is installed?

Oh but I might be interested in how *you* characterise *my* remarks, Rosemary. And I don't place the same value on privacy that TK does, so I don't labour under the same constraints if I get tired of you throwing shit in my direction.


TK has made a number of claims that you seem to believe are defamatory or actionable but you are thwarted by his anonymity.


Tell me which claims specifically and where I agree, ill repeat them and you are free to pursue me. Get on with it.

THANK YOU evolvingape.  I take it then that you are more than willing to allow HARTI to disclose your address?  Does he have this?  Or are you going to make that available as well?  We still need that in order to address our complaint appropriately.

Until you perform a definitive battery draw down test my "Edited for accuracy" comment is perfectly valid based upon all available data. After all you have been at this for 15 years and have never performed the test yet, despite claiming you have, because you cannot do simple math.

Additionally, if you think I am going to provide you with my address after you have made death threats to TinselKoala, you are clearly insane.

Why would harti have my address ? You nuts woman ?
