This part of the patent is interesting.
From:-
Shark repelling device including pulse generator producing electrical field in water between widely spaced electrodes
The pulse generator is energized from a suitable source of DC potential, and will operate on low voltages from a quarter of a volt up to 110 volts, although preferably it is energized by a single low voltage battery and, with an input amperage of about 0.75 ampere, an output voltage of about 150 volts and producing a current of up to 1,500 amperes is provided.
The 150 volts at 1,500 amperes is astonishing.
@Claudio264918 This is the pulse generator from the above patent. It’s pretty crude as a circuit. No idea what value the components are and I won’t even try to guess. The transformer would be custom made. The Control of Sharks patent that @Jeff105671 linked is much more detailed, not about to look into it; it’s pretty complex.
The Shark Shield may be nothing like these but the mention of 150 volts in the patent makes me think the person who wrote the User Guide did not understand volts and current.
Thanks to @Jeff105671 for the patent link. Makes interesting reading.
Cheers
