| Summary: | 碩士 === 中原大學 === 電機工程研究所 === 98 === Since the requirements for both regulation and standard on power quality and current harmonics are more strict in recent years, many switch mode rectifier techniques are widely adopted. There are many different kinds of basic types for switch mode rectifier. Three-phase six-switch topology in three-phase supply power system is often used in the equipment of the communication industry due to the facts that it has better power quality, lower current harmonics, and higher reliability; also, it is suitable for need in high power application.
Adopting hard switching in switch mode power supply technology would cause low efficiency and high electromagnetic interference. In this thesis, there is an analysis and design for a soft-switching scheme that contains zero voltage switching and zero current switching. This analysis and the design combined with a three-phase six-switch topology rectifier creates a new three-phase soft-switching rectifier which would have characteristics of stable output voltage, high efficient, high power density, high power factor, and low electromagnetic interference.
