TL;DR: This paper will propose a single-phase transformerless inverter circuit being composed of the association of two step-down converters, which is possible to achieve a high level of efficiency and reliability.

TL;DR: A transformerless three-phase inverter designed for the integration into a special type of a photovoltaic (PV) module, which is capable of providing an output voltage of several hundred volts is presented.

TL;DR: In this paper, a comparison between circuits based on the CSI and voltage source inverter (VSI) is made, and dimensionless benchmark factors are derived. But, both topologies show constraints with respect to the provision of reactive power.

TL;DR: Reliable operation over the designed lifetime is essential for any power electronics system, particularly because the dependability of power electronics is becoming a prerequisite for system safety in several key areas, e.g., energy, medicine, and transportation.

TL;DR: In this article, a short summary of some speeches given during Seminar on Renewable Energy system (SERENE) is presented, where contributions have mainly focused on power electronics for photovoltaic (PV) and sea wave energies, pointing out some aspects related to efficiency, reliability, and grid integration.
