Due to the advantages of superior harmonics attenuation ability and reduced size, the LCL
filter has been widely adopted to interface between the inverter and the grid for improving …

With the move towards decarbonization of the energy system and increased use of
renewable generation, the number of power electronics converter interfaced resources …

The use of LCL filters is a well-accepted solution to attenuate the harmonics created by the
pulsewidth modulation. However, inherently LCL filters have a resonance region where the …

Active dam** is a common way to stabilize the current control of LCL-filtered converters. In
this paper, the stable region of-180° phase crossing is first identified within a predefined …

Multiresonance phenomena occur in inverter clusters under weak grid, with more complex
resonance characteristics. Traditional suppression methods are difficult to determine control …

A key factor in the design of power electronic converters is the development of control
systems and, in particular, the determination of their stability. Due to ease of application, the …

Filter-based active dam** (AD) without additional sensors has been widely used in LCL-
type grid-tied inverters. For the resonance problem of the LCL filter, the AD filter is devised …

This paper presents the design of a discrete-time control scheme for the current injected into
the grid by a single-phase voltage source inverter (VSI). The VSI is connected to the grid by …

This paper proposes a novel sliding mode observer (SMO)-based compound sliding mode
current control (CSMCC) strategy with active dam** for the single-phase grid-tied inverter …

Filter-based active dam** is a promising solution to tackle the resonance hazard of LCL-
filtered inverters. Although various methods have been developed, it still lacks guidelines to …
