Patent number: 9987930Abstract: A railroad network (10) having a track (12), a network energy supply (14) and a plurality of trains (16) that are connectable to the network energy supply (14) via means (20) for connecting the train (16) to the network energy supply (14) and each have an internal energy storage system (24) for receiving and storing energy originating from said train (16) or from trains (16) of the railroad network (10) and for supplying energy to said train (16) or to trains (16) of the railroad network (10). Each train (16) is able to switch from an operational state in which it is able to move along the system of rails (12) and an idle state in which it is unable to move along the system of rails (12) and vice versa. At least one of the trains (16) of the railroad network (10) is in the idle and energized state at the same time, its internal energy storage system (24) being connected to the network energy supply (14).Type: GrantFiled: March 5, 2013Date of Patent: June 5, 2018Assignee: ALSTOM Transport TechnologiesInventors: Robert Periot, Jose Saiz, Dominique Jamet

Patent number: 7479693Abstract: One of the aspects of the present invention is to provide a power semiconductor device, including a first substrate having a first circuit pattern formed thereon, and a second substrate having a second circuit pattern formed thereon. The first substrate has a first center line extending along a predetermined transverse direction. At least one power semiconductor chip is mounted on the first circuit pattern of the first substrate, and has at least one chip electrode opposing to the second circuit pattern of the second substrate. Also, a plurality of first conductive connectors on the first circuit pattern is provided for electrical connection with the second circuit pattern of the second substrate. The first conductive connectors are arranged symmetrically in relative to the first center line of the first substrate.Type: GrantFiled: September 8, 2005Date of Patent: January 20, 2009Assignees: Mitsubishi Denki Kabushiki Kaisha, Alstom Transport SAInventors: Makoto Kondou, Kiyoshi Arai, Jose Saiz, Pierre Solomalala, Emmanuel Dutarde, Benoit Boursat, Philippe Lasserre

Patent number: 6836125Abstract: A method of testing a power module including a control gate, an emitter, a collector, at least one power component on a dielectric substrate and a diode connected in antiparallel with the power component measures partial discharges occurring between the emitter and the collector when an alternating current voltage source superimposed on a direct current voltage source is connected between the collector and the emitter of the power module. The voltage Vtest received by the power module between the collector and the emitter verifies at all times the condition Vtest>0 so that the diode never conducts. The power component is maintained in a turned off state during the test by a direct current voltage source connected between the control gate and the emitter.Type: GrantFiled: July 23, 2002Date of Patent: December 28, 2004Assignee: AlstomInventors: Fabrice Breit, Sorin Dinculescu, Emmanuel Dutarde, Thierry Lebey, José Saiz
