Provides the highest level of protection against all power disturbances (noise, spikes, frequency shifts), but is more expensive and slightly less energy-efficient due to constant double conversion.

Activates when utility power fails completely or fluctuates beyond the AVR's corrective range. shemy raboty ibp

Incoming AC power is immediately converted to DC (rectifier) and then back to perfect AC (inverter). The load is always powered by the inverter. Provides the highest level of protection against all

Depending on the architecture of the UPS, there are three primary operational schemes: , Line-Interactive , and On-line (Double Conversion) . 1. Off-line (Standby) Scheme This is the simplest and most common scheme for home PCs. The load is always powered by the inverter

When voltage falls outside a specific range or fails entirely, a mechanical switch transfers the load to the internal battery and inverter.

An evolution of the standby UPS, often used for small office networks.
