My name is Doug and I just turned 67 years old. My father was an electronic engineer and I learned a lot from him. I just didn't like sitting at a desk, so I went for more hands on careers. I got into the body shop business painting cars. That's when I needed to run three phase motors. I had bad results with my first two commercial converters. I had a static converter and a rotary converter and they didn't work very well. I looked for a better solution and found the transformer converter. It worked great and I sold information on it for years. When I retired I decided to put some more time in to the information and do more experimentation. One of the things I noticed in the years of selling information was the amount of misinformation. Many times a person asks a question and people pipe in with their best answer. The problem is their best answer is not the best answer for the person seeking information. Many times I recommend that a person just buy a commercial converter. But which type of commercial converter? The more you learn about the three phase conversion process the more of an educated choice you can make. If it is to build your own converter you have come to the right place. This book is packed with information on what works and how to build a multitude of converters. Hope you enjoy the book and learn a lot.
