< Vector diagram and simulation in Bypass operation>
Followings are describing the bypass operations in normal and power cell failure cases using
vector diagram and simulation.
Normal operation
In figure 3-16, the line voltage becomes 380V, 5-output voltage levels by serially connecting 2
power cells for each phase. At this time, voltages of 3 phases should be balanced. Fight side of
figure 3-16, output line voltages (Vab, Vbc, Vca) and the output current of RL load are shown.
