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.
Better protection against brownouts than Off-line models, with a reduced frequency of battery use, extending battery life. 3. On-line (Double Conversion) Scheme 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 Depending on the architecture of the UPS, there
Activates when utility power fails completely or fluctuates beyond the AVR's corrective range. there are three primary operational schemes:
