The fifth plan was desirable one for the development of medical barrier fabrics with fine comprehensive properties. In this plan, one-layered texture with differential face, which made fibers disposed in three layers, was selected as texture of upper and inferior layers, therefore the difficulties of weaving were reduced. Moreover, because superfine fibers with better performance and higher price were disposed only in liquid-repellent layer and ordinary polyester filaments with smaller fineness and lower price were disposed in inferior layers, the thickness and cost were reduced based on fine liquidrepellency.

Some circuits use resonant, quasi-resonant, and/or multi-resonant techniques. However, voltage or current stresses in these converters are higher and require the devices of higher VA rating. Some circuits use passive snubbers or active clamp techniques. However these converters become more complicate. Phase-shift ZVS technique has been used in bidirectional DC/DC converters since it can realize ZVS for all switches without auxiliary switches.

The thesis mainly researches on the single phase AC/AC converter in the topologies including AC_Buck and AC_Cuk. Firstly, the operating principles of the two converters are analyzed in detail and the rules of their parameters design are educed; The commutation of their power switches which is the key of these topologies to realize is analyzed in detail and a feasible solution which can be named RCD-Commutation mode is presented and proved effectual by theory analyses and simulation results.

It was found that electrical field strength and potential around the the sample changed less in the fully insulated chamber than in conducting material phytotron, so it is closer the real condition. Based on the design, the first fully insulated large artificial climate chamber in China, in which temperature , humidity, and atmospheric pressure can be regulated, has been built in our laboratory. The paper developed an insulation parameters automatic test system of high voltage capacitive equipment based on LabVIEW. In the chamber, On-line tanδmeasurements of the capacitive transformer bushings were completed. The effects of environmental factors on tanδwere analyzed, and the curves between the tanδand the environment parameters were acquired. Then, a grey relational model to analyze the effects of main environmental factors on tanδwas built, and the grey relational grade between them was gained in this paper.
