FIGURE 4-2:
Model Initialization.
The three-phase voltage source component used in the model accepts parameters:
Amplitude, Frequency, and Phase offset. As shown below, the variables defined in the
initialization are passed to the voltage source. This approach allows the line conditions
to be available to the other model blocks. The phase offset can be set to any value. The
default value shown below was selected to reduce simulation time as the PFC is not
enabled until after a zero-cross is detected.
