SISTEMA DI CONTINUITA' PER ALIMENTAZIONE ELETTRICA

摘要

An improved uninterruptible power supply system includes a converter for converting alternating current voltage into a direct current voltage; an inverter for modulating the direct current voltage outputted from a battery or the converter; a first switch for switching the voltage modulated at the inverter; a second switch for switching the alternating voltage inputted via a bypass line; an integrated transformer for increasing or decreasing the output voltages of the first and the second switches, the transformer also acting as a reactor for shaping the output voltage of the first switch; and a condenser for shaping the waveforms of the output voltage of the integrated transformer.
