Instructions for adjusting the resonance
The secondary coil for power transmission
creates a parallel resonant circuit with a
capacitor, which must be tuned to the
frequency of the power generator, so that the
best possible efficiency is achieved. This
(switchable) capacitor is installed in the power
module; the capacity is variable between 150
nF and 470 nF.
With the "test set-up" (see wiring diagram on
the right) you can optimize the resonance.
If the lowest capacitance (both switches
open) is still insufficient to provide a good coil-
to-powerhead distance, the coil should be
experimentally decreased by one turn.
If the largest capacity (both switches closed)
is insufficient, the coil should be increased by
one turn.
Allowed voltage range between VMM and VBB
This voltage is the (rectified) internal operating voltage of the power module.
The absolute maximum value of this voltage is 60 volts DC , and under no circumstances should it be exceeded. Therefore,
during initial start-up, the power head should not be brought too close to the secondary coil, and then slowly approached to
the coil while observing the voltmeter.
The minimum value is 18 volts DC [TBD]. Below this value, a function of the power module is no longer guaranteed.
The ideal voltage should be in the range of about 25 volts to 40 volts DC.
Relationship between switch setting and
capacity
Once the optimal capacity has been found,
the required connections can be fixed with a
three-pin female connector. This socket
connector must have solder bridges as shown
in the wiring diagram on the right, and must
be plugged on the middle three post pins (on
the bottom row of posts). A socket connector
with high insertion force must be used, so that
it can't get lose in operation.
