hello,
i need to design a fan controller that will change the fan speed with a potentiometer using a PV panel as power source. because the output voltage of pv panel is not stable, which ranges from 12V to 24V.
and the operation voltage of fan is from 11V to 30V.
how can i make sure the controller can supply 11V-30V to the fan at any time of daylight.
or state another way, the controller is able to regulate the voltage from 11 to 30V at any level input voltage (12-24V).
i wanna use a buck boost converter or flyback converter to achieve it.
but i can figure out how can i deal with the unstable input voltage.
thanks in advance.
