  • Patent number: 11121642
    Abstract: The disclosure discloses a simplified space vector modulation method for multi-lever converters, and relates to the field of space vector modulation methods for multilevel converters, which solves problems that a redundant on-off state is greatly increased along with increase of a number of levels in a traditional SVM technology, and SVM is difficult to realize due to calculation of the redundant on-off state and selection of a proper on-off state. The method includes the following steps of: step 1: establishing a vector expression; step 2: establishing a reference vector trajectory model; step 3: respectively representing reference signals and level signals by coordinate components of a reference vector and a basic vector and corresponding component sums; step 4: constructing a star-connected multilevel converter; step 5: sampling a phase voltage reference vector trajectory model of the star-connected multilevel converter, and synthesizing the reference vector.

  • Publication number: 20210258178
    Abstract: A novel method for performing replication of messages in a network that bridges one or more physical networks to an overlay logical network is provided. A physical gateway provides bridging between network nodes of a physical network and virtual machines in the overlay logical network by serving as an endpoint of the overlay logical network. The physical gateway does not replicate messages from the bridged physical network to destination endpoints in the overlay logical network directly, but instead tunnels the message-to-be-replicated to a designated tunnel endpoint in the overlay logical network. The designated tunnel endpoint in turn replicates the message that was tunneled to it to other endpoints in the overlay logical network.

  • Publication number: 20210236696
    Abstract: The disclosure discloses a tissue-engineered nerve transplant and a preparation method thereof, and belongs to the technical fields of biomaterials and tissue engineering. By optimizing the specification of stripes, the stripes can independently induce EMSCs to differentiate to myelination cells (Schwann cells) to the maximum extent so as to obtain an EMSCs/biomaterial scaffold compound. The EMSCs/biomaterial scaffold compound can not only be used as a three-dimensional cell culture model for researching neural stem cell differentiation, nerve fiber growth and myelination molecular mechanisms in vitro, but also be used as a tissue engineering transplant for in-vivo transplantation to repair nervous system injury.
