I am designing a boost converter for a microgrid as an university project. It is supposed to interface a 2.4kW 120V solar array (using MPPT) with a 380V DC bus. There will be other sources and loads connected to the bus.
My professor have told me to have 5% current ripple regulation for the converter. Therefore I am trying to choose a suitable inductor value, but I am stumped as there seem to be 2 equations to use.
Equation 1:
versus
Equation 2:
As you can see, I would very much prefer to use the values of equation 2 since they are much smaller than equation 1. My supervisor also told me not to overrate the inductor. But I think I do need to confirm and understand the equations to use when interfacing between a bus and a solar array, which is why I am seeking advice from the experts here.
