Output of svpwm is va, vb, vc. but i need 6 gate pulses

In designing FOC for PMSM i have 3 SVPWM output as Va, Vb, Vc. (i) but i need 6 gate pulses.

(ii) PMSM model accepts current input not voltage . I dont have any choice other than using universal bridge in between svpwm and PMSM

Muhammad Usama

for FOC of PMSM u need to used VSI(volt source inverter) with having six Mosfet/IGBT for switching and that is known as 2 level 3 phase inverter in which 2 Mosft/Igbt are short so u at a time one switch will work to provide the output..so as u got 3 switching signal through svpwm u just need to use NOT gate to reverse the signal with doing that u will 6 output signal through svpwm that help for switching and providing the supply to PMSM.
