Control method and prototyping of the Multistage Stacked Boost Architecture (MSBA)

This paper includes a look into the resonant phenomena of the Multistage Stacked Boost Architecture and a dedicated control method for the MSBA converter to handle these resonances. A linearized fast feed-forward control relying on the feedback of the output current was implemented for the boost stage and the MSBA stages. This was verified by simulations as well as measurements with a low voltage prototype.
