Book Description
Wave energy conversion devices are a rapidly growing interest worldwide for the potential to harness a sustainable and renewable energy source. Due to the oscillatory nature of ocean waves, the power generated from a permanent magnet linear generator (PMLG) for ocean wave energy conversion is pulsed. Focusing on direct drive technology, the PMLG directly translates the motion of the waves into electrical energy. The power generated, left unconditioned, is not easily used or stored. With conventional diode rectification topologies, line currents can not be controlled easily, resulting in an uncontrolled generator output and force. With an active rectifier topology, the real and reactive power from the PMLG is fully controllable. This thesis will investigate the generator modeling and design of a novel three-phase active rectifier topology and force controller with a dc-dc converter for bus voltage regulation. An in depth analysis for the controller design and simulations are presented. Hardware for the three-phase active rectifier is specified and built with initial lab test results. The controller design is implemented with National Instruments0́9 LabView and compiled on a CompactRIO real-time controller.

Book Description
EVALUATION OF OCEAN-ENERGY CONVERSION BASED ON LINEAR GENERATOR CONCEPTS As the world continues to demand greater productivity and lifestyle enrichment through technological advancements, the demand for electrical power is predicted to escalate dramatically. Thus far, this increased demand has been primarily supplied from fossil fueled plants. Unfortunately, the burning of fossil fuels produce harmful carbon dioxide pollution as a by-product. It has been hypothesized that unless a clean, renewable, and efficient alternate source of energy is found soon, the world may either exhaust its supplies of energy-producing materials or drastically degrade its environment. However, motions that occur naturally, such as ocean waves, can play a significant role in generating environmentally safe and economically viable energy for human utilization. The focus of this work predicts the electrical power generation capabilities from a seabed mounted linear generator tethered to a floating buoy heaving under the influence of passing ocean surface waves. Mathematical models are introduced which simulate the oceans' surface conditions under both the regular (basic) and irregular (natural) wave regimes, the heave (vertical displacement) response for a floating buoy, and the resulting electrical output parameters of the linear generator. Within these models, various physical and electrical parameters are altered in an attempt to generate a greater output power for a given sea state condition, making the Wave Energy Converter (WEC) more efficient. It is shown theoretically that the buoy can be designed to have a greater heave response than that of the height of a passing wave resulting in an increase in generated power from the linear generator. Author Information: Dr. Michael A. Stelzer is a Certified Project Manager and Senior Electronic Technician with a Ph.D. in Electrical and Computer Engineering. During his career to date, Mr. Stelzer has published four additional educational titles and has been admitted into Cambridge Who's Who top 101 industry experts.

Book Description
This book introduces readers to two major sustainable applications of linear synchronous machines: wave energy conversion and magnetic levitation train technology. To do so, it begins with a state-of-the-art review of linear machines, covering induction and synchronous topologies and their applications, with a particular focus on sustainable applications. This is followed by an analysis of the electromagnetic modeling of linear synchronous machines, the goal being to investigate their main features, especially their force production capabilities.

Book Description
Interest in permanent magnet synchronous machines (PMSMs) is continuously increasing worldwide, especially with the increased use of renewable energy and the electrification of transports. This book contains the successful submissions of fifteen papers to a Special Issue of Energies on the subject area of “Permanent Magnet Synchronous Machines”. The focus is on permanent magnet synchronous machines and the electrical systems they are connected to. The presented work represents a wide range of areas. Studies of control systems, both for permanent magnet synchronous machines and for brushless DC motors, are presented and experimentally verified. Design studies of generators for wind power, wave power and hydro power are presented. Finite element method simulations and analytical design methods are used. The presented studies represent several of the different research fields on permanent magnet machines and electric drives.

Book Description
As the energy demand increases and climate change becomes a major problem, the solution to decrease greenhouse gas emissions and mitigate the effects of climate change involves increasing the use of sustainable and renewable sources to generate electricity. However, developed renewable sources have inconveniences that make them incapable of generating the totality of the electricity that a country demands. Wave energy is an alternative renewable energy source that can help mitigate the inconveniences of other renewable sources and decrease the emission of greenhouse gases. This study aims to find the potential of linear generators in wave energy by analyzing the output based on different wave conditions. The study uses a numerical simulation verified by experimental data to optimize the output of the linear generator. Based on the current results, it can be stated that adding magnets increases the output, and that the maximum output greatly varies based on the coil configuration. The main external factor that improves the output is a short wave period.
