blockSVPWM

Space vector PWM

Extends from Partials.SVPWMbase (Space vector PWM base).

Information

This version uses models from the library 'MotorControl', author Martin Kuhn, DLR Munich.

Space vector modulation for AC_DC 3-phase inverters, asynchronous mode.

  |v_AC| = u*sqrt(2/3)*v_DC     AC voltage norm

  u[1] ≤  sqrt(3)/2 = 0.866: pure sine-pwm,
  sqrt(3)/2 ≤  u[1] ≤  1:  overmodulation (not implemented in this preliminary version).
  u[1] = sqrt(3)/2 corresponds to AC single-phase amplitude = v_DC/sqrt(3)

  gates[1:2]     phase-module a
  gates[3:4]     phase-module b
  gates[5:6]     phase-module c
