Incoming AC power is immediately converted to DC (rectifier) and then back to perfect AC (inverter). 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. shemy raboty ibp

Activates when utility power fails completely or fluctuates beyond the AVR's corrective range. Incoming AC power is immediately converted to DC

Because the inverter is always active, there is zero transfer time when the power fails. Activates when utility power fails completely or fluctuates

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.

The UPS passes utility power directly to the connected equipment while simultaneously charging the battery.
