I looked at the articles you linked, and will update the article some time tomorrow. So, may be take a look at it, and do not hesitate to tell me what you think or edit the article yourself. Thank you for your help. Spaceel 15:12, 17 October 2007 (UTC)

[edit] VFD Regeneration

Hi Cowie. I added this to the variable frequency drive Talk...

There really should be something about regenerative braking in the main article. Cowie, can you do it? --Treekids 20:18, 4 December 2007 (UTC)

[edit] My references

My references are mostly rather old, but they are still good references for the fundamental principles of their respective subjects.

[edit] Bose -- Adjustable Speed AC Drive Systems

This is a compilation of IEEE papers with a perface and introduction by the editor. [1]

[edit] Campbell -- Solid-State AC Motor Controls Selection and Application

This book provides a basic description of the construction, operation, selection and use of AC motors and motor control equipment. [2]

[edit] Fitzgerald, Kingsley, Umans -- Electric Machinery

This is a much cited text book. [3]

[edit] GE SCR Manual

This is a product tutorial and application manual that includes some data sheets for specific products. Although it is from 1972, the fifteenth anniversary year of the introduction of the silicon controlled rectifier, eBay sales indicate that it is still popular. [4]
