TLDR
A simple method to connect various PV modules in order to improve power quality and the PV interleaving becomes simple and efficient in terms of dynamic performances, steady-state condition and well regulated output voltage is proposed.Abstract:
In the present paper, an application of interleaved dc-dc converter in photovoltaic (PV) modular system has been presented. In the multi-string technology, several PV strings are interfaced with their own dc-dc converter to a common dc-ac inverter. Enlargements are easily achieved since a new string with dc-dc converter can be plugged into the existing platform. This paper proposes a simple method to connect various PV modules in order to improve power quality. Thanks to the proposed digital control method, the PV interleaving becomes simple and efficient in terms of dynamic performances, steady-state condition and well regulated output voltage.read more

TL;DR: In this paper, a distributed photovoltaic (PV) power plant includes a plurality of distributed dc-dc converters, which are configured to switch in coordination with one another such that at least one DC-dc converter transfers power to a common dc-bus based upon the total system power available from one or more corresponding strings of PV modules.

A review of single-phase grid-connected inverters for photovoltaic modules
TL;DR: In this article, the authors focus on inverter technologies for connecting photovoltaic (PV) modules to a single-phase grid and categorize the inverters into four classifications: 1) the number of power processing stages in cascade; 2) the type of power decoupling between the PV module(s) and the single phase grid; 3) whether they utilizes a transformer (either line or high frequency) or not; and 4) the kind of grid-connected power stage.

Rong-Jong Wai,Rou-Yong Duan +1 more
TL;DR: In this article, a high step-up converter with a coupled-inductive switch is investigated, where a passive regenerative snubber is utilized for absorbing the energy of stray inductance so that the switch duty cycle can be operated under a wide range, and the related voltage gain is higher than other coupled inductor-based converters.
