  • Publication number: 20230124688
    Abstract: A method for producing a power semiconductor module arrangement includes: arranging at least one semiconductor substrate in a housing, each semiconductor substrate including a first metallization layer attached to a dielectric insulation layer, the housing including a through hole extending through a component of the housing; inserting a fastener into the through hole such that an upper portion of the fastener is not inserted into the through hole; arranging a printed circuit board on the housing; arranging the housing on a mounting surface, the mounting surface comprising a hole, wherein the housing is arranged on the mounting surface such that the through hole is aligned with the hole in the mounting surface; and exerting a force on the printed circuit board such that the force causes the fastener to be pressed into the hole in the mounting surface so as to secure the housing to the mounting surface.

  • Patent number: 11533824
    Abstract: A method for producing a power semiconductor module arrangement includes: arranging a semiconductor substrate in a housing, the housing including a through hole extending through a component of the housing; inserting a pin or bolt into the through hole such that an upper end of the pin/bolt is not inserted into the through hole; arranging a printed circuit board on the housing; arranging the housing on a heat sink having a hole, the housing being arranged on the heat sink such that the through hole is aligned with the hole in the heat sink; and by way of a first pressing tool, exerting a force on a defined contact area of the printed circuit board and pressing the pin/bolt into the hole in the heat sink, wherein the defined contact area is arranged directly above the pin/bolt.

  • Patent number: 8981553
    Abstract: A power semiconductor module includes a first printed circuit board having a first insulation carrier, and a first upper metallization and a first lower metallization applied to the first insulation carrier on mutually opposite sides, and a second printed circuit board having a second insulation carrier and a second upper metallization applied to the second insulation carrier. The second printed circuit board is spaced apart from the first printed circuit board in a vertical direction oriented perpendicular to the opposite sides of the first insulation carrier. A semiconductor chip is disposed between the printed circuit boards and electrically conductively connected at least to the second upper metallization. The first lower metallization and the second upper metallization face one another. The first printed circuit board has a first thick conductor layer at least partly embedded in the first insulation carrier and which has a thickness of at least 100 ?m.

  • Publication number: 20130285712
    Abstract: A method for driving a controllable power semiconductor switch, having a first input terminal and first and second output terminals coupled to a voltage supply and a load, the first and second output terminals providing an output of the power semiconductor switch, includes adjusting a gradient of switch-off edges of an output current and an output voltage of the power semiconductor switch by a voltage source arrangement coupled to the input terminal. A gradient of switch-on edges of an output current and an output voltage is adjusted by a controllable current source arrangement that is coupled to the input terminal and generates a gate drive current. The profile of the gate drive current from one switching operation to a subsequent switching operation, beginning at a rise in the output current and ending at a decrease in the output voltage, is varied at most within a predefined tolerance band.

  • Patent number: 7839185
    Abstract: A method and circuit arrangement including driving a field effect controlled transistor. One embodiment provides a first load terminal, a second load terminal and a control terminal. The control terminal is driven, at least during a Miller plateau phase of the transistor, with a pulse-width-modulated control signal whose period duration is shorter than the duration of the Miller plateau phase.
