The paper presents a controller design for grid-connected inverters (GCI) with very small dc-
link capacitance that are coupled to the grid via an LCL filter. The usual controller designs …

Three-phase active damping LCL-type grid-connected converters are usually used in
distributed power generation systems. However, serious inrush current will be aroused …

In three-phase grid-tied inverter, grid voltage feedforward is helpful to improve grid-tied
power quality for strong grid condition. This paper found that the voltage feedforward had …

Adjustable speed drives (ASDs) equipped with 18-pulse converter front end provide input
disturbance rejection and clean power quality in various practical applications. In recent …

Distributed generation is gaining greater penetration levels in distribution grids due to
government incentives for integrating distributed energy resources (DERs) and DER cost …

The growing development of distributed generation and storage devices has allowed the
growth of micro-grids in low voltage and medium voltage grids. This caused the increase of …

The preordained time delay in digital controlled power electronic converters has a
substantial impact on the overall system's stability as it will vary the phase-frequency …

In the grid-tied inverters with LCL type output filter, inverter-side and grid-side current control
schemes suffer from stability issues due to the control delay and filter resonance. Weighted …

The grid-connected inverter is the key interface in the distributed power generation system.
To realize a high-quality grid current of the inverter, at least, the sensors for one current and …

Resumé Med et globalt stigende elektrisk energiforbrug samt et ønske om en markant
reduktion i nutidens CO2 aftryk, kræves der nye løsninger i forhold til produktion og …
