Electric OU: Tar Baby Cooks Some Turnip Stew: High Heat with "NO CURRENT FLOW"
Or is it really? It all depends on how and where…. AND WHEN …. the measurements are made. Here I show a “significant discovery”…. the use of the Triangle or Ramp-shaped gate drive pulse. I believe that certain of the RA scopeshots (available at seani.justemail.net ) may have been made using a triangle ramp stimulus to the gate drive rather than the usual square or rectangular pulse. SCRN0243 is an example that can be found at the link above. The NERDs always neglect the issue of the pure DC power during the non-oscillation portions of the signal. As far as I can tell they have also never made high heat in the load using purely the negative bias oscillations without turning on the Q1 mosfet at all. This is easy to test, since we know how easy it is to run the circuit that way. The effect of offset and amplitude of the triangle ramp is interesting. I was able to show high heat pulses in the load oil that continued well after the stimulation was removed. It was easy to get the oil to go over 100 degrees (just after the end of this video, which was getting long already. As I type this the oil is at 110.5 degrees C.) This of course is due to the “thermal inertia” or rather the large thermal mass of the oil, which takes a while to equilibrate when the resistor stack is warmed by the increased current.
