Single phase converters
Single phase converters
(OP)
Has anyone ever found any information about how a single phase converter works. I am looking for the technical info behind it. If there is a website or book that someone knows of that would be great
thanks

RE: Single phase converters
On the North American continent, “phase converters” seem to have a cottage-industry foundation. There are an assortment products that are marketed for various semi-niche ‘mom & pop’ applications, like very rural broadcast transmitters, CNC mills and laser interferometers.
Their viability seems to be indirectly based on various electric utilities’ line-extension rules and fees.
Mindful that they are a hawking their wares, you can find bits and pieces at sites like:

http://home.earthlink.net/~ojmsmith/indexd.html
http://www.capacitorconvertors.com/staticinstructions.pdf
[There are also FAQ-like articles linked in usenet metalworking and woodworking newsgroups.]
Many smaller VFDs have the capability of 1ø input, 3ø output that function as phase converters with additional control functions [and limitations.]

1. Single phase to three phase. These are essentially AC-DC-AC converters similar to 3phase AC-DC-AC converters except the AC-DC conversion (rectification) is single phase instead of three phase. The hardware for single phase to dc conversion is simpler than three-phase to dc conversion (rectification).
2. Another type of single phase converters are single phase converters, AC-DC-AC for single phase loads, e.g. single phase motor variable speed drives.
3. Another single phase converter AC-DC-AC is a frequency converter, e.g. 50Hz to 60Hz, 60Hz to 400Hz, etc.
To narrow down the topic, it would be nice if the original posting was elaborated on to become more specific.

etc. If this is acceptable, the further engineering and design may be pursued.
