Block modulation, 3phase
Diagram of BlockM

Extends from Partials.BlockBase (Block modulator base).

Information

Block (rectangular) modulation for DC_AC 3-phase inverters.

  ampl(v_AC_abc) = v_DC/2     AC phase-voltage amplitude

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

The default-value

  width = 2/3
corresponds to '2 phases on, one phase off'.

The input vPhasor[1] has no influence on this model. It is only needed, if additional PWM is desired.
