blockPWMasyn

Sine PWM asynchronous mode, 3phase

Extends from Partials.PWMasynBase (Sine PWM asynchronous base).

Information

Pulse width modulation for AC_DC 3-phase inverters, asynchronous mode.

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

  u[1] ≤  1 for pure sine-modulation, but u[1] >  1 possible.
  u[1] = 1 corresponds to AC single-phase amplitude = v_DC/2

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