From time 45:33 until 46:08 in your You-Tube video, the armature is spinning but the Arrows are not changing direction.
That is very wrong & very misleading.
Finally, at time 46:09, the video shows an actual Voltage reversal.
Initially, I was only answering your question regrading your...
OK, I see now that it is not a commutator but two slip rings = AC generator.
Initially, the video does not show the alternating current - which is wrong and very confusing!
Finally at time 46:43, the video does show that the current flips to the opposite direction, once every 180° = once per N-S...
That You-Tube video is of a DC Generator, not an AC Alternator with magnets on the rotor.
In an AC Alternator ... as the North Pole is leaving the stator coil, the following South Pole is simultaneously approaching the coil.
A N-S pair passes the coil, then a S-N pair passes the coil, then a...
Since there appears to be no answer, I will try ...
I will start with - I disagree with your above assumption.
AC Alternator ...
When the North Pole of the rotor passes by the coil,
the motion is always in one direction - the rotation of the rotor.
Causing the "+" half cycle voltage in the...
What if you installed a wall mounted electronic 230 Volt Variable Speed Fan Controller inside the J-box?
And then permanently set the output to 50% Power?
Something like this ...
SPEED_CONTROLLER
In this model, I do not like that "OFF" goes directly to "HIGH", instead of "OFF" to "LOW".
Does...
Can you post the schematic diagram of your circuit ?
You can you use ...
a) A Full H-Bridge or
b) A Half H-Bridge or
c) A single MOSFET
Are you designing a LC Resonant circuit?
This example pre-built device, does come with a 12 Volt 700ma (output) option.
Wireless-Charging
Some units are...
On further thought ...
The passive Diode does not allow for +5 Arduino and 12 volts on the Gate.
So use a transistor, a mosfet or a gate driver - your choice
Also consider,
a) Minimum Dead-Time
b) Gate drive current
The Arduino forum has many threads regarding H-Bridges.
PIN #1 (SW) of the MT3608 is a Low Active MOSFET only, it does not source any current - it is not a Gate Driver - it is the "PWM switch".
I assume you are trying to add an external MOSFET?
Please, post a schematic.
And then clearly explain ...
How you are going to use the MT3608 to Source...
He is saying, the current design is 4 LED'S in series per string at 1 amp
Then ...
4 strings = 4 amps
8 strings = 8 amps
16 strings = 16 amps
The design can be changed from 4 LED's in series per string, to 3 LED's in series per string, to allow more overhead voltage.
But then 33% more "3 LED"...
Good luck finding an "inexpensive" relay with contacts that are rate at 250 Volts DC at 10 Amps.
A relay with contacts that are "AC Rated" only, will not work.
Why not just leave the panels always connected as "6S" and
use a "250 Volt Input to 48 Volt @ 30 Amp output" MPPT Charge Controller...
