Stability Improvement of Grid-connected Converter with LCL Filter based on Capacitor Current Active Damping by Computational Delay Reduction
Nowadays, LCL filters utilization to suppress the grid-connected inverter switching harmonics is expanding and various methods such as capacitor current active damping scheme could be investigated to damp out these harmonics. However, the computational delays including control system, and PWM switching delays have significant effect on damping system stability. In most of LCL filter parameter d...
متن کاملCapacitor Current Feedback-Based Active Resonance Damping Strategies for Digitally-Controlled Inductive-Capacitive-Inductive-Filtered Grid-Connected Inverters
Inductive-capacitive-inductive (LCL)-type line filters are widely used in grid-connected voltage source inverters (VSIs), since they can provide substantially improved attenuation of switching harmonics in currents injected into the grid with lower cost, weight and power losses than their L-type counterparts. However, the inclusion of third order LCL network complicates the current control desi...
متن کاملA Grid-connected PV Power Supply based on Flying Capacitor multicell converter with modified MPPT based Control for Active Power Filtering
This paper presents a grid connected photovoltaic system, which acts as both power generator and active power filter (APF), based on Flying Capacitor Multicell (FCM) converter. Increase in the number of output voltage levels, natural self-balancing of flying capacitors and dc link voltage and lower power rating of components are the main futures of FCM converter compared with conventional multi...

متن کاملH∞ Repetitive Control Based on Active Damping with Reduced Computation Delay for LCL-Type Grid-Connected Inverters
In the paper, the H∞ repetitive current control scheme based on active damping along with the design method is proposed for three-phase grid-connected inverters with inductor-capacitor-inductor (LCL) filters. The control scheme aims to reduce the harmonic distortion of the output currents and achieve better efficiency. The design method introduces capacitor-current-feedback active damping into ...
