UPS system working principle popularization
The working principle of the UPS system is based on the principle of energy storage and conversion. The system consists of three main components: battery, inverter and rectifier. Batteries are used to store energy, and inverters and rectifiers are used to convert stored energy into usable AC power.
The UPS system works based on the storage and conversion of energy to provide emergency power to the load in the event of a failure of the main power supply.
Depending on the type of load and the level of protection required, UPS systems can be designed to operate in different modes. The most common ways to operate include:
Standby mode:
In this mode, the system is inactive until the system is powered off. When the system is powered off, the UPS switches to the battery power supply to provide backup power for loads.
Line interaction mode:
In this mode, the UPS system continuously monitors the input power supply and adjusts the voltage and frequency as needed to keep the output voltage stable. When the system is powered off, the UPS switches to the battery power supply to provide backup power for loads.
Online mode:
In online mode, the UPS continuously supplies power to the battery through the inverter circuit. The main power supply is only used for battery charging, and the UPS system always provides a stable, clean output voltage to the load.
