Complete modulator and inverter, 1-phase

Extends from Partials.AC_DC_base (AC-DC base, 1-phase).

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

  u[1] &le  1 for pure sine-modulation, but u[1] >  1 possible.
  u[1] = 1 corresponds to:  AC amplitude = v_DC
For block modulation:
  ampl(v_AC) = v_DC
  w     relative width (0 - 1)
  the relation between AC and DC voltage is independent of width
