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 ... -
Flywheel energy storage system based on boost DC-AC converter
( http://dx.doi.org/10.1049/cp.2011.0194 , 2011 , Conference Paper)An additional DC-DC boost converter is used in conventional configuration of Flywheel Energy Storage System (FESS) to regulate the output voltage during flywheel low speeds. This paper presents a new FESS based on the boost ... -
Investigation of inter feeder power flow regulator: Load sharing mode
(2010 , Article)The Inter feeder Power Flow Regulator (IFPFR) proposed in this paper consists of several voltage source inverters with common dc bus; each inverter is connected in series with one of different independent distribution ... -
Investigation of inter-line dynamic voltage restorer with virtual impedance injection
( IEEE , 2010 , Conference Paper)The Inter-Line Dynamic Voltage Restorer (IDVR) consists of several voltage source inverters connected to different independent distribution feeders with common dc bus. When one of the inverters compensates for voltage sag ... -
Modular Multilevel Converter-Based Bipolar High-Voltage Pulse Generator with Sensorless Capacitor Voltage Balancing Technique
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Article)In order to generate bipolar high-voltage (HV) pulses across certain load from HV dc (HVdc) power supply, a voltage source inverter (VSI) stage should be inserted between the load and the supply. In order to meet the ... -
Multiple-module high-gain high-voltage DCDC transformers for offshore wind energy systems
( IEEE , 2011 , Article)Renewable energy sources, such as offshore wind farms, require high voltage gains in order to interface with power transmission networks. These conversions are normally made using bulky, complex, and costly transformers ... -
Switched mode power supplies for charge-up, discharge and balancing dc-link capacitors of diode-clamped five-level inverter
( IET , 2010 , Article)Inductor switch mode power supplies (SMPS) operated in a discontinuous inductor current mode are used to balance the dc-link capacitor voltages of a diode-clamped five-level inverter. The SMPS concept is extended to charge ... -
Three-wire bipolar high-voltage direct current line using an existing single-circuit high-voltage alternating current line for integrating renewable energy sources in multiterminal DC networks
( Institution of Engineering and Technology , 2016 , Article)When compared with conventional point-To-point high-voltage direct current (HVDC) systems, multiterminal HVDC (MTDC) systems are more economical and flexible. MTDC systems can tie distributed high power renewable energy ...
