针对双向LLC谐振变换器高压侧启动时产生的巨大浪涌电流可能造成的器件损坏的问题,阐述了启动频率大于谐振频率的必要性和启动频率下的工作模态,并分析了相应的启动初始时刻的状态平面轨迹。据此提出了一种优化谐振变换器启动初始时刻的平面轨迹和指数降频的分阶段数字混合软启动策略,搭建了一台以SPC1168为数字控制芯片的1 440 W样机进行实验,验证了所提出的数字软启动策略的有效性,相较于传统降频启动抑制启动电流的效果提高了25.6%。

Background:Large-area soft tissue defects are challenging to *** treatment methods are hampered by problems associated with injury to the donor site and the requirement for multiple surgical *** the advent of decellularized adipose tissue(DAT)offers a new solution to these problems,optimal tissue regeneration efficiency cannot be achieved because the stiffness of DAT cannot be altered in vivo by adjusting its *** study aimed to improve the efficiency of adipose regeneration by physically altering the stiffness of DAT to better repair large-volume soft tissue ***:In this study,we formed three different cell-free hydrogel systems by physically crosslinking DAT with different concentrations of methyl cellulose(MC;0.05,0.075 and 0.10 g/ml).The stiffness of the cell-free hydrogel system could be regulated by altering the concentration of MC,and all three cell-free hydrogel systems were injectable and ***,the cell-free hydrogel systems were grafted on the backs of nude ***,immunofluorescence and gene expression analyses of adipogenesis of the grafts were performed on days 3,7,10,14,21 and ***:The migration of adipose-derived stem cells(ASCs)and vascularization were higher in the 0.10 g/ml group than in the 0.05 and 0.075 g/ml groups on days 7,14 and ***,on days 7,14 and 30,the adipogenesis of ASCs and adipose regeneration were significantly higher in the 0.075 g/ml group than in the 0.05 g/ml group(p<0.01 or p<0.001)and 0.10 g/ml group(p<0.05 or p<0.001).Conclusion:Adjusting the stiffness of DAT via physical cross-linking with MC can effectively promote adipose regeneration,which is of great significance to the development of methods for the effective repair and reconstruction of large-volume soft tissue defects.
