STATIC ELECTRIC POWER CONVERTER FOR MODULATING ELECTRIC POWER EXCHANGED BETWEEN AT LEAST A VOLTAGE SOURCE AND A CURRENT SOURCE

摘要

The invention concerns a static electric power converter for modulating electric power exchanged between at least two electrical sources, comprising at least a voltage source, a current source, and at least an electrical switching cell, each switching cell including at least two static interruptors (k1) star connected on the voltage source(s), the common point of the star being connected to the current source, and said current source being closed on the voltage source(s). The invention is characterized in that at least one of the static interruptors (k1) of at least one switching cell, is an interruptor provided with two output electrodes whereof one of the state changes (for opening or closure switching) is automatic and operates exclusively at a predetermined voltage threshold other than zero when the absolute value of said voltage increases.
