Performance of a five-phase boost inverter-fed submersible induction machine
(2013 , Conference Paper)
An electrical submersible pump (ESP) motor is preferably fed from a low voltage variable-frequency drive (VFD) followed by a step-up transformer. The motor and drive connection through a long feeder usually causes over ...
Generalized theory of mixed pole machines with a general rotor configuration
(
Elsevier B.V.
, 2013 , Article)
This paper introduces a generalized theory for the operation of mixed pole machines (MPMs). The MPM has two stator windings, namely the main winding with pole pairs P1 and the control winding with pole pairs P2. The MPM ...
Modified modulation scheme for photovoltaic fed grid-connected three-phase boost inverter
(
IEEE
, 2013 , Conference Paper)
Transformer-less photovoltaic (PV) inverters are the major functional units of modern grid-connected PV energy production systems. In general, two power conversion stages are required when low-voltage unregulated photovoltaic ...
New topologies for photovoltaic-fed single-stage boost inverters
(
IEEE
, 2013 , Conference Paper)
In photovoltaic-fed applications, boosting the limited output voltage is very essential. Single-stage boost inverters can efficiently be used to interface renewable energy sources. In this paper, different topologies for ...
Sensorless field oriented control of five-phase induction machine under open-circuit phase faults
(
IEEE
, 2013 , Conference Paper)
Recently, multiphase machine is promoted to replace three-phase drives in high power safety-critical applications. Among the numerous advantages of multiphase induction machine drives, operation and self-starting under ...
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 ...
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 ...
Multi-module Bi-directional Buck-Boost Inverter-based HVDC back-to-back transmission system
(
IEEE
, 2013 , Conference Paper)
Offshore wind energy is now seen as a key contributor to the renewable energy future. HVDC technology is among the chief technologies enabling widespread use of offshore wind. This paper proposes a new configuration, namely, ...
An improved performance direct-drive permanent magnet wind generator using a novel single-layer winding layout
(
IEEE
, 2013 , Article)
Direct-drive permanent magnet (PM) generators have become a strong contender in medium and large rating wind energy conversion systems as they not only provide higher efficiency and annual energy production, but also reduce ...
Vector control of multiphase induction machine under open-circuit phase faults
(
IEEE Computer SocietyIEEE
, 2013 , Conference Paper)
Multiphase induction machine is normally controlled using rotor field oriented vector control. Under phase(s) loss, the machine currents can be optimally controlled to satisfy certain optimization criteria. In this paper, ...
