The composition and working principle of UPS

PS power supply generally consists of rectifier, battery, inverter, static switch, and control system. Usually, online UPS is used. It first converts the AC power input from the mains into a regulated DC power supply, which is supplied to the battery and inverter, and then converted back into a stable, pure, and high-quality AC power supply through the inverter. It can completely eliminate any power supply issues that may occur in the input power supply, such as voltage fluctuations, frequency fluctuations, harmonic distortion, and various interferences. The working principle diagram is shown in the figure:
