THREE-PHASE INVERTER

The topology of a three-phase inverter consists of  3 legs; each leg includes aswitch in either the up or down position. The resulting eight possible switching configurations give rise to 6 active voltage space vectors and 2 zero vectors. The animation shows a specific sequencing of the 8 states where the active vectors rotate in discrete 60^o steps.
