Notes:
1) The magnitude of the generated ac side voltage (fundamental component) depends on the DC voltage magnitude and the modulating index.

2) The power flow to the ac system is controlled through the phase of the generated PWM (ac) voltage.

3) The expected results for a 0.9 modulating index and a phase angle of 5 deg are shown in the accompanying MathCad sheet. The PSCAD results match the expected values closely.
