TL;DR: Three different isolated multi-source grid-connected PV generation systems based on a single-phase high-frequency link micro-inverter scheme are presented, showing that a Multiple-Input Single-Output system scheme presents a feasible alternative to a higher power density converter, reducing the inverter market power gap.

TL;DR: In this paper, a simulation of a three-stage three-phase solid-state transformer with an Opal OP5607 platform is presented, where the simulation model considers the complete electronic full-order circuit for the topology without the use of simplifications.

TL;DR: The design methodology proposed is based on the direct location of resonance frequencies, taking into consideration the effect of the grid impedance, and achieves the objectives without the need to increase the number of sensors, neither the use of observers.

TL;DR: Analysis and estimation of losses in the proposed system are presented showing that the inclusion of the ripple-port converter, with proper switching devices selection, in comparison with conventional electrolytic decoupling solution allows to extract the available input power and does not significantly affects the efficiency of the system.

TL;DR: In this paper, a single-phase HF-link microinverter for low-power PV applications with a simple instantaneous power modulation scheme is presented, where the topology is based on the DC/DC Dual-Active-Bridge (DAB) converter without the intermediate DC-link, which reduces the number of power processing stages.
