Similar to Off-line, but includes an autotransformer (AVR - Automatic Voltage Regulation). This allows the UPS to boost or lower incoming voltage without switching to battery power.

Incoming AC power is immediately converted to DC (rectifier) and then back to perfect AC (inverter). The load is always powered by the inverter. shemy raboty ibp

Low cost and high efficiency, but features a short "switching delay" (typically 4–10 ms) and no voltage regulation in normal mode. 2. Line-Interactive Scheme Similar to Off-line, but includes an autotransformer (AVR

The UPS passes utility power directly to the connected equipment while simultaneously charging the battery. Similar to Off-line
