IRREVERSIBLE BIFURCATION PHENOMENON IN POWER-GRID CONNECTED CONVERTER SYSTEMS
International Journal of Bifurcation and Chaos, 2012Three-phase voltage source converters (VSC) are commonly used to convert ac power from a three-phase grid to a regulated dc voltage with unity input power factor. The control of the VSC is normally achieved by an outer voltage feedback loop and a sinusoidal pulse-width-modulated (SPWM) inner current loop.

Adaptive current control for grid-connected converters with LCL-filter
2009 35th Annual Conference of IEEE Industrial Electronics, 2009This paper presents a discrete-time adaptive current controller for grid-connected pulse width modulation voltage source converters with LCL filter. The main attribute of the proposed current controller is that, in steady state, the damping of the LCL resonance does not depend on the grid characteristic since the adaptive feedback gains ensure a ...

A new bidirectional isolated converter for grid connection
2010 IEEE Energy Conversion Congress and Exposition, 2010This paper proposes a bidirectional isolated AC-AC converter for grid connection of various loads or energy sources. The converters can be utilized for interfacing renewable energy sources to the grid as well as traditional motor drives. It does not employ any line-frequency transformer, large electrolytic capacitors, and inductors to diminish the ...

Enhanced DC-Link Voltage Dynamics for Grid-Connected Converters
IEEE Transactions on Industrial Electronics, 2022Three-Phase converters are controlled to achieve sinusoidal currents in the grid side and tight voltage regulation in the DC-link. Linear controllers based on small-signal models is a well-established solution for these converters. However, the dynamic performance can be improved only to a limited extent and it deteriorates under different operating ...
