Differential Flatness of Grid-Connected EV Charging Stations With LCL Filters: Realizability Constraints and Trajectory Planning

open access: yesIEEE Access
Grid-connected electric vehicle charging stations (EVCS) commonly employ LCL filters for harmonic attenuation. Yet, trajectory planning methods typically rely on single-inductance models without providing a formal justification for neglecting filter ...

Association of Reduction in Continuity of Care During COVID‐19 Pandemic With Cardiovascular Diseases, Kidney Failure and All‐Cause Mortality for People With Diabetes: A Cohort Study in Hong Kong

open access: yesDiabetes, Obesity and Metabolism, Volume 28, Issue 9, Page 8016-8024, September 2026.
ABSTRACT Introduction Continuity of care, a critical component of high‐quality primary care, was interrupted in people with diabetes mellitus during the COVID‐19 pandemic in Hong Kong. Research on whether reduced continuity of care was associated with higher complications and mortality risks is lacking.

Active Damping of LCL-Filter Resonance Using a Digital Resonant-Notch (Biquad) Filter [PDF]

open access: yes, 2018
The LCL filter is a fundamental component which interfaces a voltage-source inverter (VSI) with a power grid, but on the other hand, it introduces a potential resonance risk which may be harmful to the system stability.

A robust design strategy for resonant controllers tuned beyond the LCL filter resonance frequency

open access: yes, 2019
LCL filter is one of the most prevailing approaches for harmonic filtering due to its premium switching order harmonic attenuation performance. However, resonance issues, which may cause system instability, are also induced by the LCL filter.

A novel robust active damping control strategy based on H∞ loop shaping for the grid-tied LCL inverter

open access: yesFrontiers in Energy Research
LCL-type grid-connected inverters have been widely used in renewable power generation due to their size and cost advantages. However, the LCL filter has a problem of insufficient damping, which may lead to power system instability. Two common methods are
