An LCL filter-based grid-interfaced three-phase voltage source inverter: Performance evaluation and stability anaylsis
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Power converters in grid connection applications commonly employ Sinusoidal Pulse-Width Modulation (SPWM) technique. Passive filters are employed in order to attenuate the generated switching current ripples and reduces ...
Stability analysis of an active-damped LLCL filter- based grid-connected three-phase inverter
(
IEEE
, 2014 , Conference Paper)
Power passive filters are a standard solution for gridcurrent harmonics attenuation. However, these types of filters may cause a resonance between the inverter and the grid. Passive and active damping techniques are employed ...
The transition arm multilevel converter - A concept for medium and high voltage DC-DC transformers
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper proposes a dc/ac converter topology where each phase leg comprises a conventional series switch valve in one arm and a series connection of half-bridge chopper cells in the other arm. Operation with trapezoidal ...
Modular multilevel structure of a high power dual active bridge DC transformer with stepped two-level output
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
This paper addresses the issues of dc voltage matching and dc fault protection in potential super-grids. An approach for high power dc-dc conversion is proposed and analyzed. A front-to-front connection of modular-multilevel ...
Multiloop control strategy for grid-interfaced three-phase voltage source inverter with passively damped LLCL-filter
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
In inverter-based distributed generation (IBDG) and similar to the conventional third order LCL filter, the high order LLCL filter is difficult to stabilize, and may cause a resonance between the inverter and the grid. ...
