TIDA-01606: Gate Signals

Part Number: TIDA-01606

Tool/software:

Hi All,

Trying to understand what the switching states of the NPC T-Type are, but I am finding conflicting information from TI. TI is identifying the HS and the DC midpoint FET and the LS and AC midpoint switching together in the first resource, while the last resource indicates that the AC midpoint and HS are the switching pair and DC midpoint and LS are another switching pair.?
