1. V and W in each bridge should be lagging U by 120° and 240°, respectively.
2. 3U, 3V, and 3W should be lagging 2U, 2V, and 2W by 20° (-20°),
respectively.
3. 4U, 4V, and 4W should be leading 2U, 2V, and 2W by 20° (+20°),
respectively.

For 60 Hz systems, 360° = 16.7 ms.
For 50 Hz systems, 360° = 20 ms.
Refer to Figure 206
