Digital notch filter based active damping for LCL filters [PDF]
2015 IEEE Applied Power Electronics Conference and Exposition (APEC), 2015 LCL filters are widely used in Pulse Width Modulation (PWM) inverters. However, it also introduces a pair of unstable resonant poles that may challenge the controller stability. The passive damping is a convenient possibility to tackle the resonance problem at the cost of system overall efficiency.
