Typically, it includes colloidal particles, amphiphiles, liquid crystals, polymers and others. The term ＂soft＂ originates from the common macroscopic properties of these systems and differentiates them from conventional ＂hard＂ materials. Over the past decades, the field of ＂soft matter＂ has progressed tremendously. Today, it is a truly multidisciplinary research endeavor bridging physics with chemistry and life science. There are many research activities all over the world that are solely devoted to the field of soft matter. In turn, the in-depth understanding of soft matter has promoted our sci- ence and technology and helped shaping our civilization as it is now.展开更多

One reason is high voltage power supplies cannot meet the requirement for ER effect. In this paper, an ER control high voltage power supply for engineering application was designed which reduced power wastage by adopting soft switch technology; lessened its volume to satisfy micromation when adopting the planar transformer and improved its response character- istic by choosing an assistant discharging circuit. Simultaneously, a simulation analysis has been carried out. As results, the output voltage of this high voltage power supply is 5 kV, and the voltage can be continuously regulated and the voltage ripple is only 0. 7 %, so the requirement of stability is also achieved.展开更多
