Figure 374. Complementary channel pair
The complementary channel operation is for driving top and bottom transistors in a motor
drive circuit, such as the one in Figure 375.
Figure 375. Typical 3-phase AC motor drive
Complementary operation allows the use of the deadtime insertion feature.
25.8.8 Deadtime insertion logic
Figure 376 shows the deadtime insertion logic of each submodule, which creates non-
overlapping complementary signals when not in independent mode.
