VFD Power Quality Problems
• Filter capacitors drain almost immediately
No energy storage
• 6 pulse front ends have no boost capability
No sag correction built in
• Kinetic buffering causes speed changes
Cannot operate at full load and power

VFD PQ Effects on Data Centers
• Time delay before chiller can be restarted
• Servers can quickly overheat
• Shutdown data center
Chiller Loses Power
9
Drive-trips take too long to restart chillers
Solutions Currently in Use
• Motor Inertia/Kinetic Buffering• Flying restart• VFD Active Front End• AC Line Sag Corrector
Sag Correction
• UPS• DC Bus Uninterruptible Power For
Drives
Outage Protection

VFD and UPS Systems
• VFD input reactance interacts with UPS inverters• Reduced efficiency due to extra conversions• Extra point of failure
VFDs not recommended with UPS Systems
