OU/COP>1 switched cap PS cct like Tesla's 'charge siphoning'

"the excess energy is manifesting both in the capacitor's stored energy and the charging energy of the associated work done in storing it - it appears that both energies need to be utilised to achieve efficiencies > 100%"


stored and work done, arent these exactly the same? (excluding resistive losses)

Sandy,

Would you mind posting your spreadsheet?

Could be where the "Overunity" is hiding !

hi alan

no, they're not - in two senses...

the text book treatment of cap charging says they should both be the same VALUE - but not the same physical energy

  eg. text book would say that to store 2 Joules in a cap requires a total of 4 Joules - 2 end up stored in the cap, 2 get dissipated as work - therefore, the efficiency of charging cap: 50%

however, i've found from experiment that although the two energies are SEPARATE they are not necessarily the same value as claimed by the text books

eg. from experiment,
  charging 196uF cap thro' 2.5mH inductor and 10ohm load:-
  (component values all measured)

charging energy (charging pulses thro' load):
  1.12mJoules

stored energy (final discharge thro' load):
  0.97mJ

both values measured & calculated from voltage waveform across the 10ohm load resistor

discharge energy confirmed by C2 final stored voltage, 3.12V:
  0.95mJ

ratio of charging to stored energy: 1.15 to 1

which is CLOSE to the same value - however,  tests with a smaller C2 cap value show a value for this ratio of approx 4 to 1

so - i think the answer to your question is - no - not the SAME energy - and no - not necessarily even the same VALUE of energy

to be fair to the text books... the equations they quote are possibly correct for continuous current flow between charged & non-charged caps

my results are showing anomalies for switched (ie pulsed) charge transfer - and adding series inductance in the CR output path

i believe the 'classical' equations are incomplete/insufficient  for these switched charge experiments - we're seeing anomalous charge gain - and therefore a charge gain MUST be accompanied by an energy gain

the measured results confirm this last statement


hi Poynt
yep, i'll send you a .XLS file (Excel 97 version, i think) with data from the results posted on the 'Latest' page on my website


all the best

hmm, never realized this, thanks for pointing out.
