Information

Four quadrant time-averaged inverter. 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.

If equivalent to sine modulation:

  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

If equivalent to block (rectangular) modulation:
Note that this component works with the fundamental of the rectangular voltage.
The method must be improved in this case (in particular in context with inductive devices).

  v_AC_eff = u*(4/pi)*sin(width*pi/2)*v_DC/sqrt(2)    AC eff voltage of fundamental

  u[1] = 1 for block modulation without pwm, 0 <  width <  1
  u[1] ≤  1 for block modulation with pwm.
  u[1] = 1 corresponds to AC amplitude = (4/pi)*sin(width*pi/2)*v_DC
