Abstract

In this paper, the three modified space vector modulation methods are suggested in order to control effectively the shoot-through time at Z-source inverter. Both the switching patterns of three modulation methods and the modulation signals with a variation of shoot-through time are analyzed. The optimum modified space vector modulation method is determined by both the control range of the shoot-through time and the symmetry of the switching pattern and modulation signal. The performances of modulation methods are verified with the simulation results with 32-bit DSP.

본 논문은 ZSI에서 shoot-through 시간을 효율적으로 제어하기 위한 변형 공간전압 변조방식으로 3종류를 제시하였다. 3개의 변형 공간전압 변조방식에 대한 스위칭 패턴과 shoot-through 시간변화에 대한 변조신호의 변화를 분석한다. Shoot-through 시간 제어 범위와 함께 스위칭 패턴 및 변조신호의 평형성 등을 고려하여 최적의 변형 공간전압 변조방식을 선정하였으며, 32비트 DSP를 사용한 실험을 통하여 그 타당성을 확인한다.
