  • Patent number: 10637458
    Abstract: The present disclosure provides a series-connected SiC MOSFET drive circuit based on multi-winding transformer coupling. The drive circuit is mainly composed of a transformer, an energy storage capacitor and a push-pull circuit. The transformer plays a role of constraining a relationship between gate-source voltages of series-connected SiC MOSFETs to ensure that a drive voltage of each SiC MOSET in series is synchronously increased and decreased, and to prevent the problem of a dynamic voltage imbalance at moments of conduction and cutoff due to the desynchrony of the drive voltages. Both the energy storage capacitor and the push-pull structure are used to ensure that the SiC MOSFETs have sufficient drive currents at the moment of conduction to achieve fast conduction of the SiC MOSFETs. Meanwhile, a discharge loop is constructed for the gate-source voltages at the moment of cutoff to ensure that the drive voltages drop in a short period of time.

  • Publication number: 20110072538
    Abstract: The use of a lignin monomer synthetic gene 4-CL encoding 4-coumarate: CoA ligase from Populus tomentosa in increasing Sclerotinia resistance and lodging resistance. The 4-CL gene is responsible for catalyzing various cinnamic acids and their derivatives to produce respective coenzyme A esters, involved in the synthesis of various downstream secondary products, and is the key gene in the regulation of lignin synthesis. Results of the study show that, increase of lignin content improves plant's resistance against pathogenic infection, enhances the stem strength of rape, and thus significantly improves the lodging resistance. Specifically, the result shows that lignin content of transgenic rape increases more than 10% compared to lignin content of recipient control; lesion extension area of transgenic plant leaves decreases around 30% compared to recipient control; and stem strength of transgenic plant increases up to around 20% compared to control.

  • Publication number: 20090270480
    Abstract: A method for prognostic or diagnostic assessment of a skin-related disorder, such as psoriasis, in a subject correlates the presence, absence, and/or magnitude of a gene in a sample with a reference standard to determine the presence and/or severity of the disorder, and/or the response to treatment for the disorder. The method enables identification of the effectiveness of candidate therapies.
