Study on a cascaded DC-DC converter for use in building-integrated photovoltaics
Boekbijdrage - Boekhoofdstuk Conferentiebijdrage
© 2018 IEEE. In this paper, a two-stage power-electronics topology is presented for use in a BIPV module-level converter, connected to a low-voltage DC microgrid. The converter is built up as a cascade of two topologies, being an interleaved boost converter and a phase-shifted full bridge. The interleaved boost converter was chosen to lower the current stresses for the components and to reduce the required input and output capacitance due to the ripple current cancellation in the in- A nd output. The full bridge is chosen for its galvanic isolation and to perform the high step-up via the transformer turns ratio. It is shown that the maximum intermediate voltage level in between both converters can be derived from the continuous conduction mode of operation. Simulations are provided that show the correct operation of the overall structure. An experimental prototype has been built to demonstrate the overall performance of the converter.
