Hi,
I'm trying to do a project on Solar Maximum Power Point Tracking as part of my final semester. I did some basic reading on the types of MPPT and found an interesting type called Constant Voltage MPPT.
https://en.wikipedia.org/wiki/Constant_voltage_method
It says that the problem associated with this type is that there is a frequent need to disconnect the circuit in order to measure the output voltage and then set the optimum voltage to 0.76 times the actual voltage of the Solar Array.
My question is if i use a timer circuit or a microcontroller with a power semiconductor device like an IGBT or a MOSFET and set the duty cycle to 0.76, will it suffice? And if yes wouldn't this eliminate the need for opening the circuit for measuring?
