Warren,
Modest talents try convincing someone else of that.
Maybe someone else here has the solution as it sounds like a great idea
to prove up cores.
Have fun with the Chinese unit when you find it, putting your house in
order comes first.
Like I mentioned before the units can be fragile, I just fixed my broken
one with new FET's, desoldering that damn new lead free solder
practically takes a blowtorch. The pancake coils require a spacer
between the windings else the capacitance goes too high and drops the
frequency. They are made to use a small air core coil to run at a
higher frequency. Even the stove coils seem to run a bit slow on these
units as I prefer them over 25 or 30 kHz as a more efficient
transmitter. They have a lot of caps in parallel, something around 6,
could try pulling out one on each side. Probably a good idea to replace
these caps with some good high Q units anyways. When you use the scope
probe set it on x10. One of the biggest problems I have with
engineering this unit is the ground loop from my scopeso sometimes keep
the ground unhooked for frequency readings.
There is a problem with the ZVS circuit in that sometimes it is stubborn
to oscillate so may require switching the power supply on and off and
endangering the fuse or output devices on the supply. Before I fried
the FET's I began working on here taking copious notes and relaying to
the group but everyone dropped interest.
I think you came upon an epiphany the other day when you mentioned the
use of MPPT charge controllers as the interface between an RV or
whatever for impedance matching to batteries.
