The aim of this course is to give electrical engineers an understanding of the design and operation of the UPS systems and how they are configured with other elements of the electrical power system to provide an uninterruptible supply to critical loads.


This course covers the selection and design of UPS systems for mission critical applications such as hospitals and data centres. The module is primarily focussed on static systems but covers rotary systems briefly.

Learning Objectives

At the end of the course attendees will have learned 

Fundamental principles of the operation of the UPS systems
Modes of operation, reliability and redundancy
The pros and cons of static and rotary systems
Benefits of modular over block systems
