Torque ripple reduction of radial magnetic gearbox using axial pole pairing
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Magnetic gearbox (MGB) is a contactless magnet-based transmission system that transmits mechanical power between two shafts. MGBs offer significant advantages over mechanical gears such as contactless power transfer, high ...
A voltage-behind-reactance model of five-phase induction machines considering the effect of magnetic saturation
(
IEEE
, 2013 , Article)
Five-phase induction machines are generally modeled using multiple dq planes or using a phase variable model. This paper considers modeling five-phase induction machines using a voltage-behind-reactance (VBR) configuration. ...
A new single tooth winding layout for a single-phase induction motor with segmented stator
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Machines with modular structure significantly simplify the manufacturing process, particularly the stator winding, and highly increase the slot fill factor. The non-overlapping concentrated winding, or single tooth winding, ...
Non-linear sliding-mode control of three-phase buck-boost inverter
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
The development of static power converters capable of transforming DC energy obtained from alternative sources into AC has become one of the main challenges in renewable energy systems. In this context, the buck-boost ...
Fault current contribution scenarios for grid-connected voltage source inverter-based distributed generation with an LCL filter
(
Elsevier
, 2013 , Article)
Inverter-based distributed generation (IBDG) is characterized by its negligible fault current contribution compared with synchronous generators due to its inherent non-overload capabilities. Thus, IBDG hardly affects the ...
Performance assessment of single and dual loops discrete PR controllers with LCL filter for inverter-based distributed generation
(
IEEE Computer Society
, 2014 , Conference Paper)
Due to the rapid growth of the electric energy demands, the necessity of involvement of distributed generation (DG) to overcome this demand became a must. When distributed generation renewable energy sources are coupled ...
A new protection scheme for HVDC converters against DC-side faults with current suppression capability
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
Two-level voltage-source converters and half-bridge modular multilevel converters are among the most popular types of HVDC converters. One of their serious drawbacks is their vulnerable nature to dc-side faults, since the ...
Medium voltage flywheel energy storage system employing dual three-phase induction machine with machine-side series-connected converters
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Flywheels as energy storage systems are good candidates for numerous power system applications such as voltage support, serving fluctuating loads, frequency regulation and renewable energy utilization. Most of these ...
Single-sensor-based three-phase permanent-magnet synchronous motor drive system with luenberger observers for motor line current reconstruction
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
This paper presents an algorithm that enables single-sensor operation of vector-controlled three-phase permanent-magnet-synchronous-motor voltage source inverter (VSI)-based drive systems. The closed-loop operation is ...
HVDC shunt tap based on series-input parallel-output DC-AC multi-module VSCs with DC voltages balancing
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Conventionally, tapping-off a small amount of power from an HVDC transmission line to a three-phase local network can be achieved using a DC-to-AC voltage source converter (VSC) followed by a step down transformer. In order ...
