| Abstract: | To improve the quality of the load voltage of the UPS, the switching frequency of the converter should be increased and the harmonic content of the output spectrum should be minimized. The modulation has been introduced into the UPS application. The principle of modulation is to use the phase difference to improve the output voltage while the load condition is changed. The simulation result shows that the stability of the output voltage is improved. |
