A Study on Indirect Vector AC Current Control Method Using Matrix Converter Fed Inductin Motor : 매트릭스 컨버터를 사용한 유도전동기 간접 백터제어를 위한 전류제어기법에 관한 연구

다국어 초록 (Multilingual Abstract)

Three-phase Matrix Converter has become an effective substitution for the conventional converter module due to generation of the feasible variety of frequency and amplitude output voltage without energy storage elements besides the advantages such as unity input power factor at the power supply and the regeneration capability. For that advances, this master thesis describes works investigated the operation of the matrix converter fed induction motor using a first proposed indirect vector ac current control method, and then a second modified method respectively. Some simulation and experiment results are carried out to validate the effectiveness of the two-proposed methods as compared with the classical method using voltage source inverter.
