Line 14: [[Image:Three leg inverter.gif\|240px\|thumb\|right\|Topology of a basic three phase inverter.]] A three phase inverter as shown to the right must be controlled so that at no time are both switches in the same leg turned on or else the DC supply would be shorted. This requirement may be met by the complementary operation of the switches within a leg. iei.e. if A<sup>+</sup> is on then A<sup>−</sup> is off and vice versa. This leads to eight possible switching vectors for the inverter, V<sub>0</sub> through V<sub>7</sub> with six active switching vectors and two zero vectors. <center>
