“…The equal amplitude of (2 3) ⁄ E and a phase of (k − 1)π 3 ⁄ accomplish the active space vectors (k = 1,2, … ,6). The left two space vectors (k = 0,7) are zero vectors [13][14][15][16][17], and the inverter voltage space vectors V ̅ k (k = 1,2) are implemented for: T k = a k T ec , k = 1,2,0,7; by controlling switches, see Figure 4:…”
