  • Patent number: 10778114
    Abstract: A 3-level T-type neutral point clamped (NPC) inverter/rectifier is disclosed in which neutral point clamping is dynamically enabled/disabled responsive to load, e.g. enabled at low load for operation in a first mode as a 3-level inverter/rectifier and disabled at high/peak load for operation in a second mode as a 2-level inverter/rectifier. When the neutral clamping leg is enabled only under low load and low current, middle switches S2 and S3 can be smaller, lower cost devices with a lower current rating. Si, SiC, GaN and hybrid implementations provide options to optimize efficiency for specific load ratios and applications. For reduced switching losses and enhanced performance of inverters based on Si-IGBT power switches, a hybrid implementation of the dual-mode T-type NPC inverter is proposed, wherein switches S1 and S4 comprise Si-IGBTs and switches S2 and S3 of the neutral clamping leg comprise GaN HEMTs. Applications include electric vehicle traction inverters.

  • Patent number: 10710759
    Abstract: A method of packaging pre-filled medical devices is disclosed. The method comprises producing a packaging having a front panel and a back panel defining a compartment capable of holding one or more medical devices wherein at least one of the front panel or top panel has a portion containing a gas permeable material while the remaining portion of the pouch is gas impermeable. This gas permeable material allows gas to pass through the material and contact the one or more articles contained within the compartment or allows gas to pass through the gas permeable material from the inside of the compartment to the outside of the container. Upon completion of sterilization, the pouch is sealed and the gas permeable portion is cut away leaving the sterilized medical device enclosed in a completely gas impermeable pouch.

  • Publication number: 20200185302
    Abstract: Low inductance power modules for ultra-fast wide-bandgap semiconductor power switching devices are disclosed. Conductive tracks define power buses for a switching topology, e.g. comprising GaN E-HEMTs, with power terminals extending from the power buses through the housing to provide a heatsink-to-busbar distance which meets creepage and clearance requirements. Low-profile, low-inductance terminals for gate and source-sense connections extend from contact areas located adjacent each power switching device to provide for a low inductance gate drive loop, for high di/dt switching. The gate driver board is mounted on the low-profile terminals, inside or outside of the housing, with decoupling capacitors provided on the driver board. For paralleled switches, additional terminals, which are referred to as dynamic performance pins, are provided to the power buses.
