【 摘 要 】

Since most of replaceable resources generate the DC power or retrieve the most energy by converted to DC power and more DC loads are appearing on the market, the feasibility of low-voltage DC distribution has been discussed again recently. By applying DC distribution, conversions stages can be saved accompanied with benefits of high stability and the ease of designing UPS system. However, for nearly all distribution system is AC-powered at present, the feasibility of DC distribution system should be discussed. Moreover, AC/DC converters and DC breakers which are two important components in DC distribution system are also the issues to be discussed. Therefore, in this thesis, the feasibility of DC distribution will be investigated. In addition, the feasible topologies and design rules of converter and breakers are proposed with the verification by simulation results.
