Podal, Pavel ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
The objective of this work is to inform readers on classification of Uninterruptible Power Supply (UPS). depending on the equipment for which is to be used. Voltage quality has a decisive influence on the operation of equipment. There are various common power problems that UPS units are used to eliminate. Furthermore, I described backup power sources of energy used for UPS, in partikular secondary battery. This text is about UPS technology used for critical applications, witch must not fail due to a power outage or other power anomalies too.
