Current Control and Active Damping for Single Phase LCL-Filtered Grid Connected Inverter by Mohammad Alshiekh, Alaa Marouf, Muhieddin Kubeitari

“…However, the resonance in this filter causes stability problems and must be damped effectively to achieve stability. There are some methods to damp the resonance; one method is passive damping of resonance by adding a series resistor with the filter capacitor, but passive element reduces the inverter efficiency. …”
