Recently, demand for technology for energy economy and stable supply is increasing due to the increase in power demand of loads. The amount of DC power generation using new and renewable energy is noticeably increasing, and the use of DC power supplies is also increasing due to the increase in electric vehicles and digital loads. During parallel operation to increase the capacity of the power converter, the module bus method or the method using Can communication and serial communication has significant difficulties in smooth operation due to communication time delay for information sharing. Synchronization of information sharing of each power converter is essential for smooth parallel operation, and minimization of communication time delay is urgently needed as a way to overcome this problem. In this paper, a new communication method using pulse width information is proposed as a communication method specialized for parallel operation of power converters to compensate for the disadvantage of communication transmission delay in the existing system. The proposed communication method has the advantage of being easily implemented using the PWM and Capture function of the microcomputer. In addition, the DC/DC converter for DC distribution was verified through simulation and experiment, and it has the advantage of easy capacity expansion when applied to parallel operation of various types of power converters as well as DC/DC converters.

언어의 도상성 탐구

It is said that language consists of two elements, form and meaning. Traditionally, it was thought that the relationship between form and meaning is arbitrary. It means that there is no natural and motivated relation between form and meaning. Saussurian structural linguistics and Chomskyan generative syntax are based on the arbitrariness of language. They foreground syntax dealing with the structure of form and background semantics dealing with the structure of meaning. In this thesis, I do not focus on syntax and semantics separately, but I study the relationship between them. To do this, a new concept of iconicity is needed. I claim that language has a characteristics of iconicity as well as arbitrariness. By iconicity, I mean that there is a natural and motivated relationship between form and meaning at some level of linguistic units. I argue that language is arbitrary at the level of individual linguistic units and iconicity of language comes out at the level of the arrangement of individual linguistic units. I study iconicity of language which comes in sight at the level of the arrangement of individual linguistic units. For this purpose, chapter 2 studies arbitrariness and iconicity separately. And in chapter 3, I investigate the phenomena of iconicity in language, considering two hypothesis of iconicity, isomorphism and motivation. Isomorphism is that there is one-to-one correspondence between form and meaning. Motivation is that form motivates meaning and the difference in meaning is reflected by the difference in form. And isomorphism is the precondition of motivation. There are several significances in this study. The first is the following. In addition to arbitrariness, language has the characteristics of iconicity. Of course, arbitrariness is shown at the level of individual linguistic units, and iconicity is shown at the level of the arrangements of individual linguistic units. The second is that the arbitrary distinction of syntax and semantics disappear in the view point of iconicity of language. Form and meaning is placed on the one-to-one correspondence, form motivates meaning, and the difference in meaning is reflected by the difference in form. In this respect, form and meaning is closely related to each other. And syntax studying linguistic forms and semantics studying linguistic meanings cannot be separated. The third is that I can modify the Saussurian paradigm of sign into a new paradigm. In Saussurian paradigm of sign, form (signifiant; sound image) is associated with, or invokes meaning (signifié; concept), and meaning is associated with, or invokes form. And the associative relationship between form and meaning is bidirectional. But in my argument, meaning is reflected by form, but form is not reflected by meaning. In other words, the relationship between form and meaning is unidirectional.
