Capacitor-Current-Feedback Active Damping With Reduced Computation Delay for Improving Robustness of LCL-Type Grid-Connected Inverter
TL;DR: In this article, a capacitor-current-feedback active damping with reduced computation delay is proposed, which is achieved by shifting the capacitor current sampling instant towards the PWM reference update instant.
Journal ArticleDOI
Step-by-Step Controller Design for LCL-Type Grid-Connected Inverter with Capacitor–Current-Feedback Active-Damping
TL;DR: In this paper, a simple step-by-step controller design method for the LCL-type grid-connected inverter is proposed, and the complete satisfactory regions of the controller parameters for meeting the system specifications are obtained, and from which the controller parameter can be easily picked out.
Journal ArticleDOI
Optimized Controller Design for $LCL$ -Type Grid-Connected Inverter to Achieve High Robustness Against Grid-Impedance Variation
TL;DR: The optimal design of the capacitor-current-feedback coefficient is presented and a phase-lag compensation for the loop gain is proposed in order to improve system stability for a resonance frequency of (fs/6).
Journal ArticleDOI
Grid Synchronization Systems of Three-Phase Grid-Connected Power Converters: A Complex-Vector-Filter Perspective
TL;DR: A generalized second- order complex-vector filter and a third-order complex- vector filter are proposed with the CVFM to achieve better dynamic performance or higher harmonic attenuation of the grid synchronization systems.
