The converter can be improved just by exchanging the position of the resonant inductance and the transformer such that the transformer is connected with the lagging leg. The improved converter has several advantages over its counterpart, e.g., the clamping diodes conduct only once in a switching period, and the resonant inductance current is smaller in zero state, leading to a higher efficiency and reduced duty cycle loss. The operation principle of the improved converter and the comparison with the original converter are analyzed in this paper. The effect of the blocking capacitor in series with the transformer or resonant inductance is discussed, and a best scheme is determined.The improved converter is adopted to design the DC/DC converter of secondary power supply in HVDC power system.

本文将谐振电感和变压器交换位置，使变压器与滞后桥臂相连，这样箝位二极管在一个开关周期中只导通一次，同时零状态时谐振电感电流较小，有利于提高变换效率和减小占空比丢失，本文分析改进后变换器的工作原理，并与改进前的变换器进行对比，讨论隔直电容在不同位置对变换器工作的影响，确定一种最佳工程方案。

This paper introduces the drawing method of utilizing center projection to make the common position and the declined intersecting line of the declined cone .

We can attains some conclusions in this paper, Nozick emphasizes the rightness of property holding and historic justification of the origin of property, Rawls highlights on the right of equality and cares for people who live in inferior position. Nozick stresses the ownership of natural development of property "holding" and advocates the theory of "the minimal state". In order to arrive at goals of social justice and good, Rawls tries to reduce the gap in social and natural chanciness, and insists on the redistribution of property under the interposition of the public reason and public power.

我们可以获得一些结论：诺齐克看重财产持有的正当性和财产来源的历史意义，罗尔斯则按照"两个正义原则"对公共资源进行分配并关怀弱势群体；诺齐克强调财富"持有"的自然生成的所有权并主张干预财富分配的"最弱意义国家"理论，罗尔斯则试图减轻自然和社会"偶性"方面的差距，强调通过公共理性和公共权力来干预财产的分配和再分配，以期达到社会的公正与善。
