  • Publication number: 20240098389
    Abstract: An electronic device includes an interface configured to receive telemetry information for one or more power semiconductor devices and a data acquisition and processing unit. The data acquisition and processing unit may be configured to increase a gate voltage above a maximum permitted level for each of the one or more power semiconductor devices having a current slew rate that exceeds a predetermined level as determined by the telemetry information. The data acquisition and processing unit may be configured to increase a gate voltage above a maximum permitted level for each of the one or more power semiconductor devices having a temperature that exceeds a predetermined level as determined by the telemetry information. An electronic system that includes the electronic device is also described.

  • Patent number: 11889246
    Abstract: An electronic device includes: an interface configured to receive telemetry information for one or more power semiconductor devices; and a data acquisition and processing unit. The data acquisition and processing unit may be configured to periodically update an estimate of a remaining lifetime of the one or more power semiconductor devices, based on the telemetry information collected during use of the one or more power semiconductor devices and received at the interface. The data acquisition and processing unit may be configured to adjust one or more operating parameters for each of the one or more power semiconductor devices that has reached a predetermined level of degradation as determined by the telemetry information. An electronic system that includes the electronic device is also described.

  • Patent number: 8963321
    Abstract: A semiconductor device includes a semiconductor chip joined with a substrate and a base plate joined with the substrate. The base plate includes a first metal layer clad to a second metal layer. The second metal layer is deformed to provide a pin-fin or fin cooling structure. The second metal layer has a sub-layer that has no pins and no pin-fins. The first metal layer has a first thickness and the sub-layer has a second thickness. The ratio between the first thickness and the second thickness is at least 4:1.

  • Patent number: 7932598
    Abstract: A semiconductor module has a housing (2) and a metal base plate (3). A reliable yet easily producible force-transmitting connection between a semiconductor module and an external heat sink is provided by a mechanical pressure-proof counterpart (4) which is incorporated into the housing (2) and forms a firm connection (14) with a pressure-proof connecting element (10) on the base plate side. The connection is provided with a passage opening (12) for fastening the semiconductor module to the heat sink.

  • Patent number: 6828600
    Abstract: A power semiconductor module is presented in which terminal elements are press-fitted into openings in a plastic housing. This measure improves the reliability of the internal bonds between the substrate and the terminal element since there is no longer a risk of the terminal elements loosening in the plastic housing.
