- About 10 or 15 years ago, I remember reading advertising literature from
- a company called Wanlass. They had invented a unique kind of transformer
- and power supply (with the trademark of Paraformer or Parax?). This
- transformer was built differently than ordinary transformers, in that
- one winding was rotated 90 degrees from another winding. The literature
- went into the theory of how this transformer utilized a "parametric"
- term in the transformer equations, which in most other cases was ignored.
- (If I'm not quite right on these details, it has been a long time since
- I have seen the literature.) The transformer was claimed to have
- better regulation than other transformers.
-
- Does anyone remember this company or have any of their literature? This
- is strictly a curiosity search to satisfy a discussion among my fellow
- engineers.
-
- I called a company which had bought the patent rights and the name
- "Paraformer": Adtech Power in Anaheim CA, but the engineer there said that
- they had been bought and sold several times and that the paraformer
- technology was "dead". He didn't have any information on it. I suppose
- that todays switch-mode power supplies have eliminated the need for the
- paraformer technology.
-
- If anyone has any remembrances, experience or literature on this product,
- I would appreciate hearing from you. Please send E-mail since I don't
- read this news group very often. Thanks in advance.
