Abstract:
1. A static electrical energy converter intended to modulate the electrical energy exchanged between at least two electrical sources, comprising at least one electrical voltage source ( 1 ), one current source ( 2 ), and at least one electrical switching stage, each switching stage having at least two static switches (k 1 , k 2 ) star-connected to the voltage source ( 1 ), with the common point of the star connected to the current source ( 2 ), and said current source being connected back to the voltage source ( 1 ), wherein, in said static converter, at least one of the static switches (k 1 , k 2 ) of at least one switching stage, called switch with automatic switching, is a switch provided with two output electrodes ( 3 , 4 ) of which at least one of the changes of state (providing opening or closing switching) is automatic and is operated exclusively at a predefined voltage threshold other than zero when the absolute value of said voltage increases.
