1 Three-phase inverter (GIF)

Description: The topology of a three-phase inverter consists of 3 legs; each leg includes a switch 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° steps.
