    • Inverter is modulated based on first, second, and third switching states determined according to a reference vector represented as a sum of a remainder vector connecting the reference vector with a first vertex of a modulation triangle and a set of vertex vectors connecting a center vertex of space vector diagram with the first vertex. A first switching state of the inverter at the first vertex is determined based on angles of vertex vectors in the set. A second switching state of the inverter at a second vertex of the modulation triangle and a third switching state of the inverter at a third vertex of the modulation triangle are determined based on the first switching state and the remainder vector.
    • 基于根据表示为将参考矢量与调制三角形的第一顶点连接的余数向量和连接中心顶点的顶点矢量的集合的参考向量确定的逆变器被调制,所述第一,第二和第三切换状态 空间矢量图与第一个顶点。 基于该组中的顶点向量的角度确定第一顶点处的逆变器的第一切换状态。 基于第一切换状态和余数向量,确定逆变器在调制三角形的第二顶点处的第二切换状态,以及在调制三角形的第三顶点处的逆变器的第三切换状态。
