| Summary: | The fast-growing demand for renewable energy
has stimulated the rapid development of semiconductor devices
and power electronic converter technologies. The grid�connected inverter has turn out to be normal in any distributed
generation system. LCL filter is commonly adopted to
interconnect an inverter to a utility grid, owing to its parametric
performance. However, the common issue regarding resonance
frequency and design constraints complexity remains unsolved
entirely. In this paper, a simple LCL filter design to address
these issues is proposed. A ripple current minimization
approach is adopted in the systematic design process to
determine optimized reactive components’ value and mitigate
its resonance frequency. Design feasibility is simulated in the
Matlab/Simulink environment and extensive experimental work
was carried out to validated the results against the IEC61000-3-
2 standards. |
