At present, renewable energies represent 25% of the global power generation capacity. The
increase in clean energy facilities is mainly due to the high levels of pollution generated by …

Typically, parasitic capacitances exist between the ground and the solar panel terminals in
grid-connected PV systems. These parasitic capacitances provide a path for a leakage …

This article proposes a 1-ϕ transformer-less inverter for grid-tied PV systems. The proposed
inverter has the capability to produce five distinct voltage levels at the output stage …

Multilevel inverters are becoming more and more popular in photovoltaic applications
because of lower total harmonic distortion, lower switching stress and lower electromagnetic …

This article presents a novel single-phase inverter with six switches and five levels that
shares a common ground and does not require a transformer. The proposed inverter is …

Multilevel inverters are preferred solutions for photovoltaic (PV) applications because of
lower total harmonic distortion (THD), lower switching stress and lower electromagnetic …

This article studies the benefits of the virtual-ground (VG) connection for single-phase
transformerless grid-tied inverters, which is used to mitigate the leakage-ground currents …

This paper studies the double-dual DC-DC buck converter composed by two buck power
stages in a double dual connection. This connection has been previously studied with the …

In this article, a new five-level flying-capacitor inverter with the increasing ability of input DC
voltage and Full elimination of the leakage current is introduced with the application in the …

Transformerless inverters for photovoltaic systems are widely used as it features low cost,
