Graham Gunderson's Energy conference presentation Most impressive and mysterious

[tinman]

It is pretty clear that is what he was trying to do.

Therefore input power is measured after the H-Bridge.

Measuring before the H-Bridge is like saying one needs to measure the AC power feeding their bench DC power supply when it is supplying DC power to a DUT. Which of course makes no sense.

Here is my take on it FWIW

If we are only looking at the efficiency of the transformer it self,then we only need to calculate the power being delivered to the transformer,and the power delivered to the load by the transformer.

If we are to decide on whether or not the transformer is OU,and can be looped to be a self runner,and produce excess energy to also run a load,then we would have to include all the components to do so,as they are all required in order to produce the OU effect of the transformer it self.

There is no point in trying to measure the top speed of a car,when it has no wheels.

Agreed,

If GG wants to loop his transformer in its present configuration, it will have to have enough excess power to not only supply a load, but the H-Bridge, logic, and synchronous diode circuits as well.

Now, is TK going to blow a gate?

to summarize ,I don't believe the Device being investigated here or its schematic share much in common with the 2015
conference claim , some have said that proper validation of the 2015 conference claim is in question and within the margin of error for such claims.

Dear All,

At the conference Graham specifically told me that this technology is vastly different than the approach employed for last year's (2015) presentation. When looking at the active element (transformer) and the support subassemblies I would have to agree.

I don't believe there is much to be gained by going back and reviewing last years work. However, you could review the DVD and get a feel for his measurement mythology.

Well, with an infinite COP (0.000 Watts input, 10 Watts output) or even just 50 to 1,  that should be easy to do, don't you think?   

Of course if that "0.000 Watts input" reading was obtained by simply disconnecting the Current monitor side of the input C-H, it may not be so easy.

(It appears to me that the instrument was set to "Auto Range" inputs. So it should not be a surprise that it was constantly trying to change ranges if the "input" signal was fluctuating or spiky. The cure for this is not to disconnect the instrument, but rather to select a higher, fixed range setting on the input side.)

But.... in Gunderson's demonstration, isn't the "output power" measured at the bulb, rather than at the output of the transformer? The transformer output, as I understand it, is being fed through the synchronous rectifier and into a large capacitor bank before it reaches the bulb.

So how's this: If you want to only include the power at the transformer input as "input"... then let's just only include the power directly at the transformer output as "output". Fair enough?  Just disconnect everything downstream of the transformer output itself and measure the output power directly at that point. This will eliminate any possible contributions to the output measurement that may come from the synchronous diode arrangement and its power supply, pre-charged capacitors, etc.
