Title:
AC/DC POWER CONVERTER WITH IMPROVED POWER FACTOR AND IMPROVED THDI
Document Type and Number:
WIPO Patent Application WO/2012/084572
Kind Code:
A3
Abstract:
The invention relates to a power converter comprising: a first controlled current source intended for controlling the current flowing on the DC supply bus of the converter, switching means connected on the one hand to a second current source (Si2) controlled and to a third controlled current source (Si3) and on the other hand to each of the input phases (a, b, c) of the converter, first control means (3) devised so as to control the first current source (Si1) controlled in such a way as to impose a current (lred_p) on the DC supply bus and second control means (30), synchronized with the first control means (3) and devised so as to control the second current source (Si2) and the third current source (Si3) in such a way as to impose a current (lt) on one of the input phases (a, b, c) selected with the aid of the switching means.
