PWM Saturation Regulation
The PWM saturation regulator monitors current distortion and adjusts
power factor compensation as required to maintain commanded bus
voltage and current.
DC to AC Transformation
DC to AC transformation converts DC equivalents into 3-phase AC
values for use in PWM.
AC to DC Transformation
AC to DC transformation converts 3-phase AC values into DC
equivalents for use in calculation.
Reference Angle Generation
The reference angle generator executes a phase-lock loop algorithm
to provide a reference angles that are in phase with those of the utility
3-phase AC line – line to neutral voltage.
