Three-phase motors are common and required for water and wastewater pumping applications in residential developments. However, three-phase electrical distribution is not common within residential sub-divisions and single-phase connections are typically the only type of electrical service available. Since single-phase motors are limited in size and application, electrical power converter devices are used in connecting single-phase utilities with necessary three-phase motor loading and types. This paper explores two novel methods of single to three-phase conversion. Each method relies on creating or deriving a third phase to complement existing single-phase, three-wire configurations. These conversion methods present advantages over existing technologies such as AC/DC/AC converters (variable frequency drives / adjustable speed drives) by reducing component count, increasing operational reliability and ease of use, yet offering the enhanced three-phase performance. The first method proposed makes use of a three-winding transformer to raise and rectify a DC bus voltage to a level required to complete the single to three-phase conversion. The second method proposed implements a fully electronic converter to reduce size, weight, and cost. An ideal three-phase voltage source case is modeled and these two cases are compared against the ideal three-phase source conditions. Each case analyzes line and motor current, as well as torque and speed profiles. Required concepts in electrical machinery, power distribution, and power electronics are discussed to familiarize the reader with the proposed conversion techniques. Some concepts are modified for application specific use, but retain basic form and functionality. Future work and additional analysis are presented at the end.

Three phase motors are a type of electric motor, and they power a multitude of things. You may encounter these motors in about any field you are involved in. From farmers to machine shop operators to business owners, sooner or later a three phase machine shows up. How do you handle that? If you don't have three phase the cost to get it is probably prohibitive. What's next? I have spent years running and testing various ways to run three phase motors on single phase power. There are a number of ways to make the phase conversion and you need to know the best way for your situation. I started with the phase conversion process in the early 90's. I had an industrial vacuum cleaner that I needed to run. The local electric shop brought out a rotary phase converter and it was unable to start the vacuum. I sought out and found a better way. It's called the transformer converter and it was cheap for me to build and worked great! I started selling information about how to build one. Accumulating a few thousand customers gave me more insight into what people needed. Which turned out to be more information. Over the years my teaching has morphed into a full answer to the question "How should I run my machines?" I should point out that many times my advice to people after hearing about their situation is to buy a commercial converter. I like to be right up front with people and for some, building your own is not the answer. In those cases I feel that I am guiding those people through a maze of information and steering them to the most logical conclusion. But what about the person that wants to build their own? That's where I spend quite a bit of time and pages in the book. There are only two types of converters you can build yourself: the transformer converter and the rotary converter. Which is best for your machines? I help you decide. But of course, I take it much further than that. I show you all the parameters of what you are going to run into and what you can get away with. How to balance a rotary converterDoes you power company meter really record what the rotary is using?What is the best way to raise the voltage to run motors at twice you power company volts? i detail five different ways to do that, one you have never heard of before. It's my own invention.How to make your own transformer out of commonly available cores.How to modify commercial transformers.I put special emphasis on my overseas customers and their unique needs. How to hook up the start relay.How to use capacitors and hook them up.How to build the transformer converter using either a transformer you made or a commercial transformer.Basic electrical principals and why the power company and motor manufacturers use three phase.Construction helps on how to save money putting a converter together.How to build a big welder or battery charger power supply.Using oil cooling to run larger motors with your homemade transformer.What is motor protection and how does a motor starter work?What is meant by service factor and ambient temperature and how that helps usTo help illustrate some of these points I have a link in the book to videos, only for book purchasers..A chapter detailing how you can make money in three phase conversion, not by making and selling converters on eBay but much bigger and potentially more profitable than that. This is pretty much a complete guide to running three phase motors on single phase power. It contains over 20 years of knowledge put into one master book. I hope you enjoy it and have fun with an exciting field of interest. Starting and running a 25 or 30 hp air compressor at home will get your blood flowing more than stamp collecting. This is an action hobby with thrilling results.

This thesis proposes new power converter topologies suitable for aircraft systems. It also proposes both AC-DC and DC-DC types of converters for different electrical loads to improve the performance these systems. To increase fuel efficiency and reduce environmental impacts, less efficient non-electrical aircraft systems are being replaced by electrical systems. However, more electrical systems requires more electrical power to be generated in the aircraft. The increased consumption of electrical power in both civil and military aircrafts has necessitated the use of more efficient electrical power conversion technologies. This book presents acomprehensive mathematical analysis and the design and digital simulation of the power converters. Subsequently it discusses the construction of the hardware prototypes of each converter and the experimental tests carried out to verify the benefits of the proposed solutions in comparison to the existing solutions.
