1高功率逆变桥开通缓冲电路能量回馈研究显示文摘本文研究高功率、高频逆变桥开通缓冲电路中的能量回馈电路。提出了由无源元件组成的能量回馈的新结构形式,详细分析了电路工作过程,给出了仿真和实验研究波形。所获结论对逆变桥实现无源无损耗统一的缓冲电路具有重要意义。何湘宁 B.W.Williams 钱照明 1997中国电机工程学报1997,17,3:8
2Microstructure,texture and mechanical behavior characterization of hot forged cast ZK60 magnesium alloy显示文摘structure with a significant reduction in casting porosity, while the texture changed to sharp basaMeasured mechanical properties of the forged alloy showed that strength did not change, howductility improved by 75%. The analysis of the fracture surface of the forged alloy under tension rea ductile fracture with dimple morphology, while the as-cast alloy displayed a brittle fracture with pores. This demonstrated that the reduction of casting defects and dendritic morphology, as well evolution of recrystallized grains, enhanced ductility, while partial dynamic recrystallization throuforging process resulted in only marginal modification of strength in the forged condition.. 2017 Published by Elsevier Ltd on behalf of The editorial office of Journal of MaterialsS.M.H.Karparvarfard S.K.Shaha S.B.Behravesh H.Jahed B.W.Williams 2017Journal of Materials Science & Technology2017,33,9:6
