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_DCFor block modulation:
ampl(v_AC) = v_DC w relative width (0 - 1) the relation between AC and DC voltage is independent of width
