Title:
METHOD AND SYSTEM FOR CONTROLLING AN ASSEMBLY OF MAGNETICALLY INDEPENDENT TRANSFORMERS, AND DATA RECORDING MEDIA COMPRISING INSTRUCTIONS FOR EXECUTING THE METHOD
Document Type and Number:
WIPO Patent Application WO2004042911
Kind Code:
A3
Abstract:
The invention concerns a method for controlling an assembly of transformers magnetically independent of one another to obtain a desired global transformation of said assembly comprising the following steps: controlling (in 84) certain switches of said assembly to produce a succession of several global transformation ratios, and adjusting (in 84) the conduction time of each of the controlled switches based on the desired global transformation ratio such that the value of the temporal average of the succession of global transformation ratios tends towards the value of the desired global transformation ratio.
