Course Duration: 2 Days

Course Description:
This two-day technical course begins with a discussion of the need for UPS systems. It then covers the relative comparisons between various UPS topologies and their modes of operation. The batteries used for UPS systems are covered next. How a battery works, their maintenance, safety and testing is throughly discussed.

A solid working knowledge of the typical electrical components found within a UPS is developed before exploring how AC is converted to DC and then inverting DC back to AC. When all of the above elements of a UPS are understood, a theoretical rectifier and inverter feedback loop are throughly discussed. This will be followed by a trouble shooting exercise. Students are given failure scenarios where they work in groups to find which circuit component has opened, shorted or significantly changed in value to produce the alarm condition described. The course finishes with a general discussion on UPS system trouble shooting.

Some working knowledge of basic electrical engineering principles is required, although this will be revised at the beginning of the course. Real-life experience in working with batteries and UPS systems will enable the workshop to be placed in context.

Satisfactory completion of the two-day version of this course satisfies the requirements of the Engineering Institute of Canada for the award of 1.4 Continuing Educations Unit credits.
