UPS topologies:

VFD - offline

UPS output depends upon supply (mains) voltage and frequency variations

Advantages: compact dimensions possible; low cost solution

VI - line-interactive

UPS output depends upon supply (mains) frequency variations, but supply voltage are conditioned (independent)

Advantages: high efficiency, low running costs, extreme wide input voltage

VFI - onine

UPS output is independent of supply (mains) voltage and frequency variations

Advantages: highest availability, protection against all supply (mains) voltage disturbances; frequency converter mode possible
