| Abstract: | The traditional UPSs were investigated in this thesis, therefore the problems of low operation frequency and low input power factors are indicated to exist in common UPS systems in recent services. Accordingly, a new control technology of IGBT/IPM-PWM-DSP, full digital high-accuracy rectifier technology, is proposed. With the improvement of circuit design and optimal selection of power elements, high reliability of UPS is gained. Therefore the issues of electric grid pollution and the interference of interfering the electronic system are settled. The input power factor is approximatly equal to 1, as a result, the design is proved to be very effective. |
