Impressed current cathodic protection is vital for combating corrosion in buried or submerged metal structures, where a reliable power supply is crucial. The use of solar energy captured by photovoltaic panels emerges as an environmentally sustainable and economically viable solution for this critical application. The paper examines the design, hardware implementation, and system performance, focusing on the integration of the Texas Instruments C2000 board which is, pivotal for the automation and success of the impressed current cathodic protection system. The developed work aims to advance the sustainability of submerged metal structures by presenting a solution combining impressed current cathodic protection with the ecological advantages of solar energy.

Already, various electric systems architectures have been proposed and investigated over the past ten years. To meet such growing demands, the automotive industry has to move to higher voltage and the 42V power-net system is the preferred option [8]. The 42V is further processed by the interleaved six-phase dc-todc buck converter system to supply power to the conventional automotive loads that are expected to remain at 14V level as well as to absorb the peak transients on the 42V bus voltage. A special DC/DC converter is therefore needed to interconnect the 14V and the 42V DC buses in the car of the future. Automotive electronics place severe demands on the performance and price of power electronic components and making the development of a suitable converter a challenging task. This paper will present the initial development of the 5kW/42V intelligent converter for automotive applications using Matlab/Simulink. (6 pages)

The iron loss effectively reduces both the output capability and possibly the life span of the machine. To limit these undesirable effects a prior requirement is to accurately assess the iron losses, and understand their nature and, ideally, their spatial location. An experimental

Techniques for data collection and analysis used in experimental situations generate large amounts of information. Therefore, careful design of computer aided data acquisition for parameter measurement is of greatest importance. The development of a full automated system for localized power loss measurement is described. In particular, the interface method is rigorously examined and potential source of measurement errors are outlined. The performance of the system is compared to a commercialised data logger.

The thermal model is, in part, dependent upon the accurate allocation of iron losses within the machine. Using the temperature time technique a more accurate loss distribution within the machine was determined. The results from the model are validated against those measured at strategic locations within the machine.

Thermal Modelling of Induction Motors Based on Accurate Loss Density Distribution

For a complex heat flow systems, such as electrical machines, the lumped parameter network technique still plays a very important role for the solution of heat flow problems. This paper discusses the development of the thermal model, taking into account the different material types and complicated geometries within the machine, as well as the different modes of heat transfer. However, to predict an accurate temperature distribution requires the knowledge of loss distribution in the machine. Using the temperature-time method a more accurate loss distribution is obtained. The model performance is validated against measured results obtained for a 4 kW, 3-phase, 4-pole, 415 V totally enclosed fan cooled induction motor.

Fuel cells are one of the future promising renewable and sustainable power sources that can be used as a clean power source for various applications such as transportation. In conjunction with large supercapacitors, fuel cells can generate high power density with a fast dynamic response, which is ideal for automotive applications. In order to design a highly efficient fuel cell system for automotive applications, an optimised model for a multi-level DC-DC converter, fuel cell and supercapapcitor is required. The analytical model for the fuel cell has been developed in order to model the interface of the fuel cell, supercapacitor and drive train to the interleaved DC-DC converter. This paper deals with the development of a detailed fuel cell model using Matlab/ Simulink where the parameters for a Ballard Mk-V fuel cell stack are used. The simulation results have been presented and discussed and the validity of the developed model is ascertained.

The main objective of this work is to study the feasibility of using the global system for small marine applications. In this paper, the global system was modeled and then simulated using Matlab/Simulink. The fuel cell is used as the main power source; each fuel cell is connected with a DC bus via a DC–DC boost converter. The Energy Storage System (HESS) is controlled as a fast-bidirectional auxiliary power source, it contains a battery and supercapacitors and each source is connected to the DC bus via a bidirectional buck-boost DC–DC converter (BBDCC). In order to optimize the HESS, the supercapacitors and the batteries are designed to allow high-efficiency operation and minimal weight. The entire system’s energy management algorithm (PMA) is developed to satisfy the energy demand of the boat. Finally, simulation tests are presented in Matlab/Simulink and discussed, where the effectiveness of the proposed system with its control is confirmed.

The Prediction of Loss Density Distribution in Electrical Machines Using a Direct ‘Inverse Field’ Finite Element Technique

Electric and Magnetic Fields, 1995

The availability of improved analytical and numerical techniques has made it possible to design electrical machines to exacting standards. This is particularly true in the design of magnetic circuits where established numerical techniques, such as finite elements, can be applied to study the magnetic field distribution in very great detail. Thermal design, however, has tended to lag behind its electromagnetic counterpart because of the considerable difficulties associated with the correct assignment of loss density distribution within the volume of the machine. These uncertainties arise as a result of the lack of total understanding about the nature and origin of iron losses. Whilst an incorrect loss density distribution may not affect the overall thermal distribution, localised temperatures could be grossly inaccurate. There have been attempts to quantify and characterise the losses using empirical methods[1], and experimental methods such as the calorimetric method[2], and the temperature-time method[3], but these have proved difficult and cumbersome and cannot be readily incorporated into general design methodologies. Furthermore the lack of information on the thermal characteristics of materials, especially when these are combined to form a composite mass, for example the copper windings which consist of copper, lacquer, air, and insulation, has compounded the problem of accurate thermal modelling.

The ability to predict an accurate temperature distribution, in turn, requires a knowledge of the iron loss distribution, thermal characteristics of the materials, and the cooling conditions, all of which are very difficult to quantify. A temperature–time method is proposed to evaluate accurately the iron loss density distribution in the stator of an induction motor by measurement of temperature gradients in the machine. This method is used to determine the iron loss density distributions, under various load conditions, in a specially constructed 3-phase, 4-pole, 4 kW frameless induction motor. Accurate stray load losses are then computed from the resulting loss density distributions. The experimental results were validated against those obtained with standard test procedures, as well as predicted results from finite element analysis.
