Ibp — Shemy Raboty

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

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

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

The request for "shemy raboty ibp" (schemes of UPS operation) refers to the different functional modes of an , known in Russian as ИБП (Источник Бесперебойного Питания) .

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 UPS passes utility power directly to the

Better protection against brownouts than Off-line models, with a reduced frequency of battery use, extending battery life. 3. On-line (Double Conversion) Scheme

Because the inverter is always active, there is zero transfer time when the power fails. The load is always powered by the inverter

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.
