An active damping technique for a current source inverter employing a virtual negative inductance
(2010 , Conference Paper)
A grid connected CSI requires a CL filter stage. In this work, the isolation transformer leakage inductance constitutes this filter inductance. This CL filter is lightly damped for efficiency constraints. Hence, it is ...
Simplified generic on-line PWM technique for single phase grid connected current source inverters
(
Institute of Electrical and Electronics Engineers Inc.
, 2012 , Conference Paper)
Mandatory restrictions for a current source inverter's (CSI's) proper operation, like continuity of the DC link current, complicate the corresponding PWM generation especially in the case of single phase systems. Classical ...
A state of the art review of control techniques for power electronics converter based distributed generation systems in different modes of operation
(
IEEE Computer SocietyIEEE
, 2013 , Conference Paper)
This paper presents an overview of the state of the art techniques in inverter-based distribution generation systems. Different control techniques and classification of inverter modules operated in grid and islanded modes ...
Brushless doubly fed induction machine as a variable frequency transformer
(
IEEE
, 2012 , Conference Paper)
Variable frequency transformer (VFT) has been recently used as an alternative to HVDC to control power flow between asynchronous networks. VFT consumes less reactive power than a back-to-back HVDC system, provides faster ...
Open loop V/f control of multiphase induction machine under open-circuit phase faults
(
IEEE
, 2013 , Conference Paper)
One of the main advantages of multiphase induction machines is their higher fault-tolerant capability. Under phase(s) loss, the machine currents can be optimally controlled to satisfy certain optimization criteria. In this ...
Control of doubly-fed induction machine storage system for constant charging/discharging grid power using artificial neural network
(
IET
, 2012 , Conference Paper)
A large-capacity low-speed flywheel energy storage system based on a doubly-fed induction machine (DFIM) basically consists of a wound-rotor induction machine, and a back-to-back converter for rotor excitation. It has been ...
Traction system with on-board inductive power transfer
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
In traction applications based on long primary and short secondary type, contactless electrical energy transmission can offer distinct advantages over the conventional energy transmission based on catenary system to provide ...
