Design and Analysis of Robust Active Damping for LCL Filters Using Digital Notch Filters
TL;DR: In this article, the effect of the phase lead or lag on the active damping is investigated, and it is revealed that when the resonant frequency drifts away from its nominal value, the phase-lead or lag introduced by the notch filter may make itself fail to damp the resonance.
Journal ArticleDOI
Highly Reliable Transformerless Photovoltaic Inverters With Leakage Current and Pulsating Power Elimination
TL;DR: A transformerless inverter topology, which is capable of simultaneously solving leakage current and pulsating power issues in grid-connected photovoltaic (PV) systems, and it is possible to use long-lifetime film capacitors instead of electrolytic capacitors to improve the reliability of the PV system.
Journal ArticleDOI
Design of LCL Filters With LCL Resonance Frequencies Beyond the Nyquist Frequency for Grid-Connected Converters
TL;DR: In this article, the authors proposed a LCL filter design method and its current control for grid-connected converters, where the resonance frequency of the filter was set to be higher than the Nyquist frequency, i.e., half of the system sampling frequency.
Journal ArticleDOI
Mitigation of Grid-Current Distortion for LCL-Filtered Voltage-Source Inverter With Inverter-Current Feedback Control
TL;DR: A simple method for the ICF control system to mitigate the grid-current harmonics without extra sensors is developed and the effectiveness of the proposed method for harmonic rejection is verified by detailed experimental results.
Journal ArticleDOI
Improved Power Decoupling Scheme for a Single-Phase Grid-Connected Differential Inverter With Realistic Mismatch in Storage Capacitances
TL;DR: It is the intention of this paper to quantify ac and dc imperfections experienced by the differential inverter when storage mismatch occurs and a simple improved scheme is proposed for raising performance of the differential inverse inverter (or the differential rectifier where desired).
