  • 본 논문에서는 3.3kW급 차량탑재형 충전기에 적합한 공진형 컨버터의 최적설계기법을 제안한다. 주어진 배터리 충전 프로파일에 대하여 대표적인 4가지 공진형 컨버터를 각각 최적의 궤적에 따라 동작하도록 하는 설계기법을 제안한다. 또한 이 충전 궤적에 따른 각 컨버터의 도통전류, 턴오프전류 등의 비교를 통하여 최적의 컨버터를 제안하고 시작품으로 타당성을 검증한다.

  • u-Park means national parks with environmentally sound information networks and integrated ubiquitous services are available. u-Park is totally managed based on u-IT (Ubiquitous IT Technologies) which provides ubiquitous service through sophisticated resources of national park and establishments. It is necessary in changing the existing park management system into u-IT based u-Park management system that park managers should accept new technology, u-Park management system, and be able to utilize it. The purposes of this research is to analyze managers' acceptance behavior on ubiquitous computing technology. Technology acceptance model (TAM) was introduced to specifies the causal relationships among variables related to managers' technology acceptance behavior. The hypothesized model was tested by surveying 157 managers at 5 national parks in Korea. TAM accounted for 55.2% of the variance in intention to use. The most important finding is that perceived compatibleness was the most influential variable in determining intention to use. This means that u-Park management system should be compatible with manager's task and business style.
