Three-phase AC-AC Power Converters Based on Matrix Converter Topology

Book Description
AC voltage frequency changes is one of the most important functions of solid state power converters. The most desirable features in frequency converters are the ability to generate load voltages with arbitrary amplitude and frequency, sinusoidal currents and voltages waveforms; the possibility of providing unity power factor for any load; and, finally, a simple and compact power circuit. Over the past decades, a number of different frequency converter topologies have appeared in the literature, but only the converters with either a voltage or current DC link are commonly used in industrial applications. Improvements in power semiconductor switches over recent years have resulted in the development of many structures of AC-AC converters without DC electric energy storage. Such converters are an alternative solution for frequently recommended systems with DC energy storage and are characterized by a lower price, smaller size and longer lifetime. Most of the these topologies are based on the structure of the matrix converter. Three-Phase AC-AC Power Converters Based On Matrix Converter Topology: Matrix-reactance frequency converters concept presents a review of power frequency converters, with special attention paid to converters without DC energy storage. Particular attention is paid to nine new converters named matrix-reactance frequency converters which have been developed by the author and the team of researchers from Institute of Electrical Engineering at the University of Zielona Góra. The topologies of the presented matrix-reactance frequency converters are based on a three-phase unipolar buck-boost matrix-reactance chopper with source or load switches arranged as in a matrix converter. This kind of approach makes it possible to obtain an output voltage greater than the input one (similar to that in a matrix-reactance chopper) and a frequency conversion (similar to that in a matrix converter). Written for researchers and Ph.D. students working in the field of power electronics converters and drive systems, Three-Phase AC-AC Power Converters Based On Matrix Converter Topology: Matrix-reactance frequency converters concept will also be valuable to power electronics converter designers and users; R&D centers; and readers needing industry solutions in variable speed drive systems, such as automation and aviation.

Book Description
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.
