- Description: Abstract:Trial and error approach which involves service interruption is usually carried out to resolve unbalance on phases in power distribution system. This approach might improve the phase voltage and current but the resultant effect (change) does not last for too long; thereby reduces the market value in terms of quality and reliability of supply. To enhance the performance of the secondary distribution system there is a need for an automating technology. The aim of this paper is to introduce a method and technology developed for resolving imbalances in a secondary distribution system as a result of the uneven distribution of single phase load across a three phase power system. The technology developed is able to monitor, acquire/display collected data and perform self changing switching actions electronically. This action is in form of rearrangement or transfer of consumer loads for optimal performance of the distribution feeder. The proposed switching technology is based on open- transition switch that enables transfer or rearrangement of consumer loads in a three-phase system within milliseconds with supervisory control system. The following methodologies: System Simulator - Matlab (Simulink), Virtual Instrumentation-Lab VIEW and Hardware implementation were applied for the validation of the proposed technique

- Description: Abstract: In this paper, a single-phase switching mode converter acting as a unity power factor rectifier and/or as active power filter with no alteration in the topology is studied. A generalised voltage control taking in consideration the output power of the DC bus is developed. To demonstrate the improved response of the voltage regulator, a battery charger as “unknown dc load” is used

- Description: Abstract: In this paper, the power transfer through a multi-purpose switching-mode converter is studied. Many authors presented the separate functions of the switching mode converters as active power filters, reactive power compensator and unity power factor rectifier. In this paper we present the simultaneity of those three functions and the capability of power transfer is discussed in detail. The results of this research are intended to be a guideline for application designers
