| Abstract Good regulation and stability are important factors to be considered in designing of the uninterruptible power supplies systems, which depend on the load requirements. On the other side, the cost factor roles the proper design selection of the uninterruptible power supply, especially for the commercial applications. A pulse width modulation uninterruptible power supplies are considered to have good features over the rival one. This paper presents a suggested method for the controlling of the uninterruptible power supplies to regulate the output voltage, by using an easy practicable, low cost, and one-sensor, microprocessor-based regulator. This regulator circuit depends on minimizing the hardware complicity with efficient software. The practical results show that a good and reliable regulation performance in the applications when the fluctuation in both input DC voltage and load occurred, such as the applications using the solar cells or batteries as the input voltage source supplying variable load conditions. 2004/12/ 2004 | ||
