GRID-FORMING/FOLLOWING CONTROL FOR CONVERTERS OF RENEWABLE ENERGY SOURCES
Have been proposed the new control framework for converters of renewable energy sources (RES-C), based on choosing their operation mode – grid-forming or grid-following in depends on the dynamic stiffness (DS) of the power system for some bus i (control ...

Analysis and mitigation of dead time harmonics in the single-phase full-bridge PWM converters with repetitive controllers [PDF]
In order to prevent the power switching devices (e.g., the Insulated-Gate-Bipolar-Transistor, IGBT) from shoot through in voltage source converters during a switching period, the dead time is added either in the hardware driver circuits of the IGBTs or ...

A review on flicker-free ac-dc LED drivers for single-phase and three-phase ac power grids [PDF]
Light-Emitting Diodes (LEDs) are coming strongly into the lighting market due to their advantages over conventional lighting solutions: energy efficient, controllable in both light and color, long lifetime, lack of a warm-up period and high power density.

Suppression of Second-Order Harmonic Current for Droop-Controlled Distributed Energy Resource Converters in DC Microgrids [PDF]
Droop-controlled distributed energy resource converters in dc microgrids usually show low output impedances. When coupled with ac systems, second-order harmonics typically appear on the dc-bus voltage, causing significant harmonic currents at the ...

Direct control strategy for a four-level three-phase flying-capacitor inverter [PDF]
A direct predictive control strategy is proposed for a three-phase four-level flying-capacitor (FC) inverter in this paper. The balancing of the FC voltages, a challenge in applications with small capacitors and low switching frequencies, is done without
