Etude et conception d'un interrupteur de puissance monolithique à auto-commutation:le thyristor dual disjoncteur.

Abstract : Systems using renewable energies, use switches with complex and bulky drive circuit. Self -controlled switches lead to simplified topologies of this power converters because self switching mode operation does not require any auxiliary power supply, external drive circuit and sensor. That's why we propose to develop, with functional integration concept, an integrated device with self-switching and current bidirectional capabilities, i.e. a self turn-off zero voltage switching mode thyristor. To achieve this function, two original topologies based on a MOS-thyristor and an IGBT are proposed. The two solutions are analyzed with 2D physical simulation and then devices are realized. The electrical characterizations show that electrical behavior of the first solution, well suited to monolithic integration, is very sensitive to technological parameters. The second topology is more interesting to validate the electrical target specifications but its integration is more difficult.
