This course gives an insight to the subject of U.P.S. (Uninterruptible Power Supply) systems. The subject of "Power Quality" is discussed and the need for U.P.S. system is emphasized. The basic circuits for U.P.S. system are explained and also various configurations shall be discussed. The concept of supply reliability is discussed and the various factors affecting reliability are presented.

The object of this course is to present and appreciate the concept of U.P.S. is discussed and the types of "Critical loads" which need a U.P.S. supply are presented. One of the main objectives is to assist the practicing engineer in selecting a suitable U.P.S. the various factors, which affect the selection of a suitable U.P.S., are discussed in detail. The selection of a suitable U.P.S. configuration is discussed and its impact on the reliability of the system is presented.

This course is designed to Electrical Maintenance Engineers, Operations Engineers and highly qualified technicians who would like to expand their knowledge of UPS systems and battery chargers.
