Modified transformerless dual buck inverter with improved lifetime for PV applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
The Dual Buck Inverter (DBI) possesses no shoot-through concerns and it can improve the efficiency by utilizing power MOSFETs. This is because at accidentally triggered shoot-through states; two inductors are in-parallel ...
Novel LCL filter for non-isolated photovoltaic inverters with CM current trapping capability for weak grids
(
IEEE
, 2018 , Conference Paper)
© 2018 IEEE. In this work, a novel LCL filter topology for non-isolated Photovoltaic (PV) applications is developed. This topology has the ability to trap the High-Frequency (HF) Common Mode (CM) current inside the PV ...
Novel shunt-less filters for grid-connected transformerless photovoltaic applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
The existing ground leakage current suppression methodologies are effective when Photovoltaic (PV) arrays' stray capacitors are small (in several nano-Farads). In such case, the High Frequency (HF) content of the inverter's ...
Electrolytic capacitor-less dual buck inverter with CM and DM active resonance damping control for Non-isolated grid-connected PV applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2018 , Conference Paper)
The shoot-through problem of conventional H-Bridge inverters imposes a threat to system's reliability and efficiency. This is because the unintentional shoot-through state short-circuits the DC-Link capacitor. To overcome ...
