    Tips: Composition of UPS power supply
    UPS power supply consists of five parts, main circuit, bypass circuit, battery and other power input circuits, AC/DC converter rectifier (REC), DC/AC transform inverter (INV), inverter and bypass output switching circuit, and battery.
    The voltage stabilization function of UPS system is usually done by the rectifier. The rectifier adopts silicon control or high-frequency switch rectifier. It has the function of controlling output amplitude according to the change of external electricity, so that when external electricity changes (this change should meet the requirement of the system), the voltage with output amplitude is basically unchanged.
    The purification function is completed by the energy storage battery. Because the rectifier’s interference on instantaneous impulse cannot be eliminated, there still exists interfering impulse of the voltage after rectification. In addition to the function of direct-current and direct energy storing, the storing battery is just as if to be connected by a large container capacitor for the rectifier. The size of the equivalent capacitance is in proportion to the capacity of energy storage battery. Because the voltage at both ends of capacitor is not mutable, it means that it plays the role of purification (also called the shielding of interference) by the smoothness properties of the capacitor on the pulse to eliminate the impulse interference.
    The stabilization of frequency is accomplished by the converter and the frequency stability depends on stability degree of converter oscillation frequency.
