A New 3-D Space Vector PWM under Line-to-Line Fault in Three-Phase Four-Wire Inverter

3상 4선식 인버터의 선간 단락 사고 발생 시 새로운 3D SVM 기법

In this paper, we propose a new three-dimension space vector pulse width modulation for three-phase four-wire inverter under line-to-line fault. In order to this method, the processes of selecting of the output voltage vectors and synthesizing the reference voltage vector are discussed. In addition, we deal with the calculation of the duty cycles for each sector. The experiments are provided to validate the effectiveness of the proposed method.
