TL;DR: In this paper, the authors describe photovoltaic (PV) module architectures with parallel-connected sub-module-integrated dc-dc converters (subMICs) that improve efficiency of energy capture in the presence of partial shading or other mismatch conditions.

TL;DR: In this article, the authors evaluate the effects of the simple voltage-balancing differential power processing (DPP) control approach on the sub-module-level maximum power point (MPP) efficiency and show that the submodule MPP efficiency of voltage balancing DPP converters exceeds 98% in the presence of worstcase MPP voltage variations due to irradiance or temperature mismatches.

TL;DR: In this paper, the authors proposed a simple control strategy for the isolated-port DPP architecture, and provided a comprehensive stability analysis for this system, which reduced the high-order system dynamics to a 1-D control loop, which allows stable, well-behaved responses using a proportional or a lag compensator.

TL;DR: In this paper, the duty cycle is driven in proportion to a voltage error, with no further processing, thus eliminating the need to measure or to control the current explicitly, and the system stability is demonstrated using the Lyapunov stability theorem.

TL;DR: In this article, a PV module architecture with sub-module integrated converters (subMICs) is proposed to improve efficiency of energy capture in the presence of partial shading or other mismatch conditions.
