Abstract
This  thesis  proposes  redundancy  and  hot-swap  features  for  paralleled
multi-inverter systems with voltage control and current weighted distribution
control (CWDC) strategy. With a CWDC strategy, instantaneous current is fed
back and monitored; thus, weighted output current distribution and fast regulation
among the inverters can be achieved for linear and nonlinear loads. Additionally,
the proposed paralleled system is equipped with the features of redundancy and
hot-swap; therefore, system power rating can be expanded readily and it has high
maintainability.   Simulation   results   and   hardware   measurements   from   a
two-inverter system with either equal or different power ratings have demonstrated
the feasibility of the proposed control scheme in fast regulation and weighted
current  distribution.  The  proposed  redundancy  and  hot-swap  features  have
improved reliability and stability of the paralleled multi-inverter system.

Implementation of Three-Phase Fed DC Power Supply System with High Power Factor

Implementation of Three-Phase Fed DC Power Supply System
    with High Power Factor

In this thesis, a high efficiency power supply system with high
power factor is proposed for high power applications. The studied power
supply system consists with a three-phase three-switch power factor
corrector (PFC) and a phase-shifted zero-voltage-transition full-bridge
DC/DC converter with current doubler rectification. High power factor
input can be achieved by the adopted PFC circuit with a simple
configuration. The phase-shifted operation of the full-bridge DC/DC
converter provides the zero-voltage-switching (ZVS) features for the
bridge switches to reduce the switching losses effectively. The current doubler rectification reduces significantly the secondary rectification losses. Therefore, high efficiency can be also accomplished. The detailed operating principle and design consideration of this power supply system are analyzed and described. A 1.1kW 55V/20A laboratory prototype was implemented  and  tested.  The  experimental  waveforms  verify  the feasibility of the proposed design. The implemented power supply system exhibits optimum performances such as high power factor, high efficiency, simple configuration and high reliability.

About me

Dr. Kamran received his M.S. and Ph.D. in Electrical Engineering from Georgia Institute of Technology, Atlanta, GA USA in 1992 and 1995 respectively. His area of research was control of power converters. Dr. Kamran has several years of teaching experience besides multiple years of electronic system design experience working in industry, both in Pakistan and in USA. He worked with Silicon Power Corporation, PA, USA on the development of next generation power converters for US Navy during 1996. He moved to Pakistan in 1997 and started teaching at GIKI. He has designed and implemented large-scale distributed computer network systems like the toll collection and access control system for the Motorway (M2) in Pakistan.

1600KV Basic Impulse Level (BIL) Testing Tower

 This is a video showing three operations of Surplec HV's BIL testing tower. The BIL is a high-voltage testing device used to create artificial lightning, in order to test the resistance of the equipment to a bolt. Most high-voltage equipment are made to whitstand an enormous amount of voltage for a short period of time, about 10 seconds. This BIL tower has a power of 1,600,000 Volts, so it is able to test equipments that go up to 345KV. Watch carefully, it strikes three times in the 11 minutes. If you blink, you'll miss it.
Watch the white tube with the windows to see the lightning at 4:32, 6:21 & 11:20.

Large Scale Integration of Micro-Generation to Low Voltage Grids

Description of the laboratory micro grids
The laboratory Microgrid system of NTUA
This report presents the laboratory-scale microgrid system, which has been installed at the National Technical University of Athens, within Workpackage H of the project. The microgrid comprises two PV generators, battery energy storage, controllable loads and a controlled interconnection to the local LV grid. Both the battery unit and the PV generators are connected to the AC grid via fast-acting DC/AC power converters. The converters are suitably controlled to permit the operation of the system either interconnected to the LV network (grid-tied), or in stand-alone (island) mode, with a seamless transfer from the one mode to the other.
