At the very beginning he points to the supply input at 295 volts 80 mA that's 23.6 Watts in DC. Now this is in disagreement with the Clark Hess negligible measurement of input power.
Output power is 9.5 Watts which looks right
A very well done professional presentation, Graham speaks the lingo and knows of what he speaks, but what about that DC input power? Am I missing something?
Nevertheless there are some interesting things going on in that presentation.
Ion, Your observation of the power supplied by the 295v dc supply of 23.6 watts is quite important and if analyzed correctly, provides a somewhat different view of the device. Graham's MIT is basically a reactive-to-real converter which means there are AC input voltage and current waveforms consuming VARS of power and producing a DC output thru some transforming means. In the MIT, the 295v DC supply feeds the current limit inductor connected to the top of the "H" bridge. The "H" bridge with it's switches and timing produces the AC input voltage and current waveforms that are connected to the primary of the MIT. It is at this point in the circuitry (the primary) that Graham's input measurements are taken as he states in the video, with the resulting high reactive var of 2.244*419 = 940.2 compared to the real input of ~.5 watts. Herein lies a potential problem not even considering the difficulty in accurately measuring an input with a reactive/real ratio of 940.2/.5 = 1880:1. The problem is, one must be able to synthesize the input voltage waveform that will produce the same current waveform in the test device or, we are deluding ourselves with the measurements. This may be difficult to understand for those who have not built and tested reactive-to-real converters, but in my experience with my own Magneto Electric Induction devices, I could demonstrate and have others replicate infinite OU that was really not OU at all. When measuring the reactive input waveforms as Graham is doing, OU is present even though as one can see, the DC power feeding the input circuitry is far greater. The DC input power measurement is accurate regardless of the measurements taken at the reactive AC input voltage and current points and I would even say the circuit design itself. This is of course my opinion and I realize it will be rather unpopular at this point but the proof will lie in the attempt to loop the MIT or by building the device with synthesized input waveforms. The frequency of ~38kHz is low enough to synthesize with current technology and I do believe Graham could do this. I do not wish to be negative, but I believe both attempts will fail! Regards, Pm
