Comments on “An Efficient Partial Power Processing DC/DC Converter for Distributed PV Architectures”

In this paper, “An Efficient Partial Power Processing DC/DC Converter for Distributed PV Architectures” by Agamy et al. (IEEE Trans. Power Electron., vol. 29, no. 2, Feb. 2014), a dc-dc converter for distributed photovoltaic plant architectures, capable of performing series-type partial power processing under maximum power point control was proposed and tested for various performance parameters. The purpose of this note is correcting (IEEE Trans. Power Electron., vol. 29, no. 2, Feb. 2014) by proving that while the overall operation and results are technically correct, the proposed converter is actually a boost stage performing full rather than partial power processing.
