Tips: Construction of 1000VA UPS Power Supply
The UPS power supply or uninterruptible power supply consists of five parts, the power input circuits including main circuit, bypass circuit, battery and others, the rectifier (REC) for AC/DC converting, the inverter (INV) for DC/AC converting, the inverter and bypass output switching circuit, as well as the battery.
The voltage stabilization function of 1kVA 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 of the UPS power supply 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 of 1000VA uninterruptible power supply is accomplished by the converter and the frequency stability depends on stability degree of converter oscillation frequency.
