3.1 Four-Phase Interleaving

Figure 3-1 shows switch nodes 1 through four showing stable permanence at 45A load. As Figure 3-1 shows, Channel 1 and channel 2 are complementary, which is produced by primary controller. Channel 3 and channel 4 are complementary, which is produced by secondary controller. Each phase is shifted 90 degrees apart.
