6 FAQs about Frequency after three-phase inverter conversion

How many switch state possibilities are there in a 3-phase inverter?

Considering inverter states in which one switch in each half-bridge is always on (for current continuity at the load) there are 23 = 8 switch state possibilities for the 3-phase inverter. We give each state a vector designation and a associated number corresponding to whether the top or bottom switch in each half-bridge is on.
