Certain additional info is needed from your circuit in order to possibly determine the source of the energies. First, what is the inductance and DC resistance of the primary and secondary windings of the transformer? What is the turns ratio secondary to primary and is the dot notation as shown below?
What type of circuit is used for the pulse source?
...

Edit: Also measuring the inductance of the 'primary aiding the secondary' and the 'primary bucking the secondary' would allow the k factor to be calculated.
Partzman,
Thanks for responding. A complete schematic is attached and here’s the data.
Electrical measurements were taken at a 100 Hz meter setting using a DEREE DE-5000 LCR meter.
Straight rod core: 2.3cm diameter. x 18cm 99% pure iron powder in a 2.5cm OD plastic tube, hand compressed, no binder.
Primary: 20 AWG, 656 turns, 12.69 mH, 2.45 DCR, 199.63 μF
Secondary: 20 AWG, 1048 turns, 34.19 mH, 5.39 DCR, 74.08 μF
The way I understand it, the dot notation you drew for the primary is correct, but I’m unsure which end the dot should be at for the secondary. If you were winding them with the core laid horizontal in front of you, start at the left end and wind the wire going away from you, under the core, up, back toward you over the top of the core then down to complete 1 turn. Continue winding toward the right until the end of the spool then wind toward the left, back and forth as needed. Both coils are wound in the same manner.
The end of the wire you started with on the primary is connected to the positive and the other end connects to C2.
There is about a 2mm gap between the iron and primary wire, and about a 3 mm gap between primary and secondary windings. The gaps are from the PLA coil spools and air space for the 20ga wire primary leads. There are 6 spools for the primary coil, but the 2 center spools are not connected to anything other than terminals. There is a 3 mm space between each primary coil too. The other 4 coils are wired in series to make the 656 turn primary winding.
I don’t know how to measure the inductance 'primary aiding the secondary' and the 'primary bucking the secondary', otherwise, I would be happy to furnish that info.
Measured capacities: C1 = 4.38 mF, C2 = 2.63 mF, C3 = 2.63 mF

PS Where should the secondary's dot be placed?
EDIT: The schematic has been replaced. The secondary's diode & cap polarity were wrong. Very sorry for any inconvenience.
