Capacitor voltage balancing using redundant states of space vector modulation for five-level diode clamped inverters
(
IEEE
, 2010 , Article)
A redundancy balancing technique for the five-level diode-clamped inverter is presented, which balances the four dc-link capacitor voltages at high modulation index and high power factor. The technique is based on dividing ...
Ride-through capability of grid-connected brushless cascade DFIG wind turbines in faulty grid conditions-A comparative study
(
IEEE
, 2013 , Article)
Doubly-fed induction generator (DFIG)-based wind turbines (WTs) are reported to suffer reliability problems due to the presence of slip-rings, brushes, and the gearbox. These disadvantages encouraged several research groups ...
Optimum power transmission-based droop control design for multi-terminal HVDC of offshore wind farms

, 2013 , Conference Paper)
In renewable energy-fed grid-connected applications, voltage source converters (VSC) offer high flexibility and system controllability features. In addition to the stepped down nature of its output voltage, the VSC is ...
DC-link capacitor voltage balancing for a five-level diode-clamped active power filter using redundant vectors
(2013 , Article)
This paper investigates the compensation and modulation processes of the five- level diode-clamped active power filter, compensating a three-phase rectified resistor-inductor load with redundant vectors. From the analysis, ...
