EM devices previous post on possible theory of operation [lighting a bulb] Quote: I am pro free energy and quite open minded, as you guys should already know by now. I have put my professional reputation on the line quite a few times at work and elsewhere on these forums. However, this time I have to discredit the claims made in this video again, like I've done in the past with these claims. From my own experiments in the past, I was able to light up a 60W light bulb to the same "full brightness" which is not full by any means, I did it with even less wattage then they claim. They claim to input 5 watts, I did it with slightly less than 4 watts. Did I claim over unity? NO, a bright bulb is not a quantitative measurement of output power. I'll tell you guys what their device is: It is an over complicated "rube goldberg" Resonant Power Converter! EM PS, Here's a good link to resonant converter topologies from Texas Instruments. http://www.ti.com/lit/ml/slup085/slup085.pdf Here's two diagrams from this document. One for Series resonant and one for Parallel resonant. On the output you always want to have a high impedance to AC currents, so you include an inductor after the diodes and before the output capacitor, else the AC currents see a short in the capacitor and the voltage drops. The rectified DC current has no problem. Impedance matching is very important! ------------------------------- resconverter01.jpg (48.04 KB, 996x372 - viewed 664 times.) resconverter02.jpg (46.25 KB, 917x363 - viewed 640 times.)
