A high performance generalized DPWM algorithm was proposed in [8], which uses SVPWM in low modulation range and GDPWM in high modulation range, but it did not change the modulation algorithm according to the load and did not calculate the power loss of the proposed algorithm.
The new SVPWM scheme using medium space vectors developed for six-phase VSI connected to a symmetrical load with a one neutral point (Fig.
En la actualidad el SVPWM se emplea no solamente para el control de motores, sino tambien para otros usos en la electronica de potencia tales como:
In SVPWM strategy the reference voltage vector in a switching cycle is equals to the vector sum of the nearest two active vectors and one/two zero vectors in an average switching period.
While in SVPWM strategy index modulation in this overmodulation zone extends from 0.
The switching algorithm of SVPWM for four-switch three phase inverter can be based on the one for six switch inverter where orthogonal plane is divided into six sectors and the formation of required reference vector is done in the same way as for six switch inverter.
And the computations, including Clarke transformation, Park transformation, current control algorithm, inverse Park transformation, inverse Clarke transformation and SVPWM, must be completed in order.
Modulation signal is generated through the Modified SVPWM technique with modulation index, [m.
The zero vectors in the inverter stage are reselected based on SVPWM strategy in [20].

Hysteresis control control methods based on voltage space methods based on voltage space vector are proposed in [7], which allow output voltage control and minimization of harmonic components, limit the current tracking error in hysteresis bandwidth; besides, a novel SVPWM approach to control DC rail resonant inverters is proposed in [8].
