One method of protecting sensitive equipment against power interruptions is the uninterruptible power supply (UPS). The UPS has become very popular as the cost of power electronics has decreased. Figure 1 shows the principles of operation of an electronic UPS. Single- or three-phase power is obtained from the power system and is rectified to DC.
There are two types of output of UPS power supply: B. Output of municipal electricity or battery (dc voltage) after passing through the inverter. Backup UPS power supply： Battery mode (B) : the output of the dc voltage after the inverter is a square wave. line-interactive UPS power supply：
Uninterrupted power supply batteries are an essential part of a UPS system. They are the stopgap measure designed to briefly supplement power when the main power source fails. UPS batteries are a key feature in the instantaneous response to power outages and are critical to the protection of sensitive electronics and devices.
Many fewer pieces of equipment have problems with modified square wave power than with straight square wave. Modified square wave output is used on many lower to middle-range UPS, and is also sometimes called "stepped approximation to a sine wave", "pulse-width modified square wave", or even "modified sine wave".
