Complete modulator and inverter, 3-phase dq0

Extends from Partials.AC_DC_base (AC-DC base, 3-phase dq0).

Information

Four quadrant switched inverter with modulator. Fulfills the power balance:

  vAC*iAC = vDC*iDC

The structure of this component is related that of a voltage source, with two minor differences:

1) theta is used instead of omega as input.

2) u_phasor is used instead of v_phasor defining the AC-voltage in terms of the DC voltage v_DC according to the following relations.

For sine modulation:

  |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

For space-vector modulation:

  |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)

For block modulation:

  ampl(v_abc) = v_DC/2
  w     relative width (0 - 1)
  w = 2/3 corresponds to 'two phases on, one phase off'
  the relation between AC and DC voltage is independent of width
