Hi all, because this thread is about DSE I will try to post question here.
I have found some documents about Don Smith devices including info about DSE
I am currently making some experiments regarding to DSE with capacitors.
Because of safety I use only relative low voltages (I want to start HV after I make some progress with experiments).
I am not 100% sure, but I think I observe that capacitor (which is the main part of DSE) is working just as Don Smith described it.
I use polarized electrolytic capacitor. On the first plate (plus) of capacitor (#1 - 2200uF 35V) is coming rectified high frequency (20kHz or 30kHz) voltage pulses about 100V (pulses come from 12V battery via wattmeter +ZVS + ferrite core coils).
The second plate (minus) is not connected to the input circuit, but instead via separated circuit (with some rectifier diodes and another capacitor (#2 2uF 50V) connected to separate grounding.
(I use ultra fast switching diodes).
I am able to charge capacitor #2 very fast to 120V (independently of the capacitor #1 which can be charged just only to 10V in that moment). If I short #2 it little bit sparks, discharges and charges again very fast. And on input measuring
I am trying different capacitors like 2uF 50V, 2200uF 35V, 4.7uF 25V, 1000uF 25v
So I made "output" circuit accross the capacitor #2 with output ferrite core. So when I short this capacitor, current goes throught the core's primary and on the secondary I see almost nothing. So am struggling with some real (at least small) output.
Here I need help. What is wrong with this output circuit - why nothing (no energy) is seen here?
My setup is like in image (input part circuit not displayed here, only incoming pulses):
I thinkg/guess another results can be obtained with high voltage (above 2000 V) and adequate capacitors and the circuit can behave differently, but I am not ready to go this way
