Abstract
Official abstract text for this publication.
The disclosed embodiment relates to a method of controlling a system including at least one inverter with six switches, which is linked to a battery, and supervised by a processor. The method implements a vector modulation, so that it is able to prevent the current linking the battery from passing through zero amperes by means of appropriate control logic. The disclosed embodiment also relates to a device for controlling an electronic component.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of controlling a system comprising at least one six-switch inverter, linked to a battery, and controlled by a processor, said method comprising the following steps: allocation of a zero time to two predetermined near active-vectors; and determination of a new reference vector on the basis of the two near active-vectors, wherein current flowing from the battery is prevented from passing through zero Amperes. 2. The method as claimed in claim 1 , further comprising a step of modifying a circular vector into another form which, as a function of the radius of a reference vector, can be transferred to the surface of a hexagon. 3. The method as claimed in claim 1 , further comprising a step of calculating the resulting zero time, and a step of allocating this time to the near vectors, by allocating k to the first vector in each sector and (1−k) to the second vector, k lying between 0 and 1. 4. A device for controlling a system comprising at least one six-switch inverter, linked to a battery, and controlled by a processor, the device comprising: means for allocating a zero time to two predetermined near active-vectors; and means for determining a new reference vector on the basis of the two near active-vectors, wherein current flowing from the battery is prevented from passing through zero Amperes by means of appropriate control logic.
