blockPWMasyn1ph

Sine PWM asynchronous mode, 1-phase

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

Information

Pulse width modulation for AC_DC 1-phase inverters, asynchronous mode.

  v_AC_eff = u*v_DC/sqrt(2)     AC effective voltage

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

  gates[1:2]     phase-module 1
  gates[3:4]     phase-module 2
