Abstract

A generalized multi-phase space vector theory is considered for developing the space vector modulation of a seven-phase voltage source inverter. The modulation is based on the control of the voltage vector in the first d-q plane, imposing to be zero the voltage vectors in both the second and the third d-q planes. The proposed switching pattern includes one-leg commutation at a time, with the possibility to share the zero voltage between the two null vectors. The maximum value of the modulation index for sinusoidal balanced output phase voltages is carried out. The theoretical analysis is confirmed by numerical simulations
