An Optimal PWM Technique for Dual-Output Nine-Switch Boost Inverters with Minimum Passive Component Count
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
Nine-Switch inverter (NSI) has been recently introduced for independent control of dual ac motors. Although this topology reduces the number of active switches by 25% compared to conventional inverters, it has a main ...
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 ...
A Family of Discontinuous PWM Strategies for Quasi Z-Source Nine-Switch Inverters
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
This paper proposes a new family of discontinuous PWM strategies to control the quasi-Z-source nine-switch inverters (qZS-NSI). The presented strategies provide buck and boost inversion capabilities, and suitable for ...
An Improved Torque Density Pseudo Six-Phase Induction Machine Using a Quadruple Three-Phase Stator Winding

, 2020 , Article)
The nine-phase six-terminal induction machine has recently been proposed as a promising contender to the conventional six-phase asymmetrical winding machine in terms of torque density, phase current quality, stator winding ...
A New Six-Phase FSCW Layout for Permanent Magnet Synchronous Wind Generators
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
This paper proposes a new non-overlapped six-phase Fractional Slot Concentrated Winding (FSCW) layout for a Permanent Magnet (PM) synchronous wind generator with an outer rotor and surface mounted magnets. The proposed ...
Multi-terminal Hvdc system with offshore wind farms under anomalous conditions: Stability assessment
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
Droop control is widely adopted to control Multi-Terminal high-voltage Direct Current (MTDC) systems with offshore wind farms. During permanent faults, the faulty line should be isolated promptly to preserve a high reliability ...
Postfault control of scalar (V/f) controlled asymmetrical six-phase induction machines

With the accelerated development in semiconductor power devices along with the dictated rigorous reliability standards in some industrial sectors, the application of a medium-voltage high-power multiphase induction machine ...
Carrier-Based PWM Strategy for Quasi-Z Source Nine-Switch Inverters
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Nine-switch Inverters (NSIs) have been proposed to accommodate the independent control of dual AC motors or in six-phase drives. This topology reduces the number of active switches by 25% compared with conventional Voltage ...
A cascaded boost inverter-based open-end winding three-phase induction motor drive for photovoltaic-powered pumping applications
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Although PWM inverter-fed drives are now a well-established technology in industrial applications, the generation of common mode voltage associated with these modulation techniques results in undesired bearing current and ...
A directional protection technique for MTDC networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper suggests a new protection algorithm for a multi-terminal direct current (MTDC) networks. The current values and directions at each bus connecting more than one line are determined. The measured values of line ...
