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

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. 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 An evolution of the standby UPS, often used

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. Off-line (Standby) Scheme This is the simplest and

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.
