Synchronization
• Why?
– To correctly provide supplemental power to
AMPS, our AC signal must be in phase with the
system
– If they are out of phase, it will alter the 3-phase
voltage lines on AMPS
Synchronization
• How?
– Phase-Lock Loop
• Fast Response
• Will accurately correct any error
– Zero-Point Crossings
• Frequency of the line
• Timings
