Abstract

The space vector control based voltage control method for a three-phase PWM rectifier requires a lot of effort to design an optimal switching pattern since a switching pattern for the switching section must be designed. In this study, a D-Q control based SPWM output voltage control algorithm was studied for the three-phase six-pulse CVS type rectifier. In the output voltage control algorithm, three-phase reference signals are obtained from the D-Q transformation based on the space vector representation method, instead of the switching pattern, SPWM method is used to generate rectifier switching control signals. Next, a three-phase six-pulse CVS PWM rectifier based on D-Q transformation and SPWM was modeled using EMTP-RV. Finally, the validity of the D-Q control-based SPWM voltage control algorithm was confirmed by comparing the output voltage waveform obtained through EMTP-RV simulation works with a reference value and confirming that the output voltage accurately follows the reference voltage.

3상 PWM 정류기에 대한 공간벡터제어 기반 전압제어방식은 스위칭 구간에 대한 스위칭 패턴을 설계해야하기 때문에 최적한 스위칭 패턴을 설계하는데 많은 노력이 요구된다. 본 연구에서는 3상 6펄스 전압형 PWM 정류기를 위한 D-Q 제어에 기반 한 SPWM 출력전압 제어 알고리즘을 연구하였다. 출력전압제어 알고리즘에서 3상 기준신호들은 공간벡터 표시법에 기반 한 D-Q 변환으로부터 얻어지며 스위칭 패턴 대신에 SPWM 방식을 이용하여 정류기 스위칭 제어 신호들을 생성하도록 하였다. 다음으로, EMTP-RV를 이용하여 D-Q 제어기반 SPWM 방식을 가지는 3상 6펄스 전압형 PWM 정류기를 모델링하였다. 끝으로, EMTP-RV 시뮬레이션을 통해 얻어지는 출력전압파형을 기준 값과 비교, 출력전압이 기준전압을 정확하게 추종함을 확인함으로서 D-Q 제어기반 SPWM 전압제어 알고리즘의 유효성을 확인할 수 있었다.
