  • Matrix converter for transforming electrical energy
    Patent number: 7170199
    Abstract: A matrix converter for transforming electrical energy between at least one voltage source, in particular a power supply network, and at least one current source, in particular a load, said converter including a matrix of switches connecting said voltage sources to said current sources, wherein each of said switches has two terminals which are interconnected via a photoconductive layer of diamond, each switch being controlled by means of a light source irradiating the layer of diamond interposed between the two terminals of the switch.
    Type: Grant
    Filed: January 8, 2003
    Date of Patent: January 30, 2007
    Assignee: Alstom
    Inventors: Emmanuel Dutarde, Christophe Beuille, Fabrice Breit, Henri Schneider
  • Matrix converter for transforming electrical energy
    Patent number: 6781854
    Abstract: A matrix converter for transforming electrical energy between at least one voltage source, in particular a power supply network, and at least one current source, in particular a load, said converter including a matrix of switches connecting said voltage sources to said current sources, wherein each of said switches has two terminals disposed in respective distinct parallel planes and a photoconductive diamond substrate interposed between said two terminals of the switch, each switch being controlled by means of a light source irradiating the diamond substrate interposed between the two terminals.
