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 ...
