Figure 3.10 - General connection diagram of a 12 pulse rectifier configuration with three parallel UR11 units
The Figure 3.10 on page 3-11 presents the general connection diagram using three parallel UR11 units
operating as a 12 pulse rectifier. The Figure 3.11 on page 3-12 presents the general connection diagram
using two parallel UR11 units operating as a 12 pulse rectifier and the Figure 3.12 on page 3-12 presents the
general connection diagram using one UR11 unit operating as a 12 pulse rectifier.
