UPS power supply

UPS (Uninterruptible Power System/Uninterruptible Power Supply), namely uninterruptible power supply, is a system equipment that connects batteries (mostly lead-acid maintenance free batteries) with the host, and converts DC power into municipal power through module circuits such as the host inverter. It is mainly used to provide stable and uninterrupted power supply for single computer, computer network system or other power electronic equipment such as solenoid valve, pressure transmitter, etc.

2. Common applications of UPS power supply

When the mains power input is normal, the UPS will stabilize the mains power and supply it to the load for use. At this time, the UPS is an AC mains voltage regulator, which also charges the battery in the machine; When the mains power is interrupted (emergency power failure), UPS will immediately supply the DC power of the battery to the load with 220 V AC power by inverting the zero switching conversion method, so that the load can maintain normal operation and protect the load software and hardware from damage. UPS equipment usually can provide protection for over voltage or under voltage.

3. Development history of UPS power supply

The UPS power supply system consists of five parts: main circuit, bypass, battery and other power input circuits, rectifier for AC/DC conversion (REC), inverter for DC/AC conversion (INV), inverter and bypass output switching circuits, and energy storage battery. The voltage stabilization function of the system is usually completed by the rectifier. The rectifier device uses silicon controlled rectifier or high-frequency switching rectifier, which has the function of controlling the output amplitude according to the change of external power, so that when the external power changes (the change should meet the system requirements), the output amplitude of the rectifier voltage is basically unchanged.
